It is preferred that 11% by weight or more be bound. This is because the dielectric constant of the polyimide resin cannot be reduced when the alkyl group or the alkylene group other than the methylene group has a chemical structure of less than 11% by weight in the molecule of the resin.

Then, an aromatic-containing addition polymerization type polyimide resin can be prepared by reacting any of the above unsaturated bis-imides and diamines having an aromatic group. The compounding ratio of bis-imide and diamine is preferably in the range of 1.7 to 2.5 bis-imide to 1 diamine in molar ratio. If the amount of bis-imide is less than 1.7, the generation of high molecular weight increases, and the curing time tends to be short, which causes a problem in handling. If the amount of bis-imide is more than 2.5, a large amount of unreacted raw material remains. Easier to do. The reaction can be performed in a state in which bis-imide and diamine are dissolved in a solvent such as N-methylpyrrolidone (NMP) or N, N-dimethylacetamide (DMAc). The reaction can be carried out in a range of about 170 to about 170 ° C, and the reaction time can be carried out in a range of about 30 to 350 minutes.

The polyimide resin composition of the present invention is prepared by adding BP to 100 parts by weight (hereinafter referred to as “parts”) of the polyimide resin.
An allyl ether of A is blended in an amount within a range of 10 to 200 parts by weight, imidazoles and organic peroxides as accelerators, and dimethylformamide (DMF), DMAc, dioxane, NMP as diluting solvents. , MEK
It is a resin composition composed of those used alone or in combination as appropriate from among others. When the amount of the allyl ether of BPA is increased, the dielectric constant of the laminate obtained therefrom tends to decrease. When the amount is less than 10 parts, the effect of lowering the dielectric constant is hardly recognized, and when the amount is less than 200 parts, When used, the dielectric constant decreases, but the laminate is hard and brittle, which is not preferable. In addition, these allyl ethers of BPA also act as a reactive diluent, and thus lower the intrinsic viscosity and surface tension of the resin composition. Therefore, the prepreg in which the resin composition permeates well between the fibers of the base material and the filling of the base material with the resin is significantly improved can be obtained. Then, in the laminated board in which the prepreg is hardened, the penetration length of the plating of the sulfol plating becomes extremely short, and at the same time, the inner wall of the sulfol finishes extremely smooth, thereby insulating the sulfol from the inner layer circuit. And the effect that the reliability of the sulfol is remarkably improved can be obtained.

In order to ensure the flame retardancy required for the safety of electromechanical devices, a brominated resin having a reactive group as a flame retardant can be added to the polyimide resin composition.
You . In particular, the amount of the brominated resin having a reactive group is 1 to 5 parts by weight based on 100 parts by weight of the polyimide resin.
It is preferable to use it in the range of 0 parts by weight. The reason is 1
If the amount is less than 50 parts by weight, the flame retardancy cannot be obtained, and if the amount exceeds 50 parts by weight, the heat resistance of the obtained laminated board is deteriorated, and the performance is lowered such as the dielectric constant is increased. Further, a brominated resin having a reactive group is preferable because a flame retardant is reacted with a side chain or a terminal group of the polyimide resin and incorporated into the skeleton of the polyimide resin structure, so that the interlayer adhesive strength and sulfo- This is because a product having both flame-retardant performance and reliability and heat resistance can be obtained.

In order to obtain a prepreg from the above polyimide resin composition, after impregnating a base material with the above polyimide resin composition, the unsaturated solvent is dried and evaporated while the dilute solvent is evaporated.
The self-polymerization of the aromatic addition polymerization type polyimide resin prepared by reacting imide and diamine and the radical reaction of the allyl ether of BPA which is a reactive diluent are advanced to semi-harden the resin composition in the base material. It was obtained.

The temperature for semi-curing is preferably from 110 to 155 ° C. Above 155 ° C, especially BPA ants
This is because the reaction of the ether proceeds too much, the interlayer adhesive strength of the obtained prepreg decreases, and the effect of lowering the dielectric constant decreases. If the temperature is lower than 110 ° C., the treatment takes a long time and is not practical. Semi-cured is in a range generally called a B stage in a curing process of a thermosetting resin,
When heat is further applied, the resin flows and a curing reaction can occur.

The adhesive strength when the layers of the laminate were peeled in the direction of 90 degrees is shown in the interlayer adhesive strength [kg / cm] of the characteristic values in Tables 1 and 2. In addition, 0.4 mmφ
The drill bit is used to make 1,000 holes at a rotation speed of 40,000 rpm and a feed rate per rotation of 50 μ / rev. Sulfur plating is carried out by a common method using both electroless plating and electrolytic plating. The cross section of the perforated hole was observed under a microscope, and the length of the permeation of the perforated plating and the wall surface roughness of the perforated surface generated during the perforated plating were measured. The results are shown in Tables 1 and 2. It is shown in the column of characteristic value. In the examples in which BPA-AE or BPA-CA was blended, the length of the plating penetration of the sulfol and the wall surface roughness of the sulfol were comparative examples in any of the examples in which the reactive flame retardant was blended. It is smaller than 1 and 2. However, in order to impart flame retardancy, in Example 11 in which the non-reactive brominated resin is blended, flame retardancy is obtained as in the case of the reactive brominated resin in Example 10, Heat resistance decreases. Due to this decrease in heat resistance,
As a result of the heat generated during drilling, the wall surface of the sulfol becomes rough or cracks occur. As a result, the plating penetration length of the sulfol and the wall roughness of the sulfol become worse as in Comparative Example 1, and B
The effect of blending the allyl ether of PA will be lost. Incorporation of a reactive brominated resin ensures flame retardancy and does not lower heat resistance. Therefore, the heat generated during drilling may cause the wall surface of the sulfol to become rough,
Since the generation of cracks is prevented, the length of plating penetration of the sulfol and the roughness of the wall surface of the sulfol are significantly reduced as compared with the comparative example.
