2. Description of the Related Art Conventionally, thermosetting resins such as epoxy resins and bismaleimide resins have been widely used as molding materials used for applications requiring high heat resistance.
However, when the heat resistance is increased, the toughness of the cured product using these resins decreases, but on the other hand, if the toughness is expressed by the stress intensity factor K IC , the epoxy resin has a K IC of 1 to 2 kg / mm.
It is about 3/2 ). On the other hand, among thermoplastic resins, those showing high heat resistance as seen in some aromatic polymers have been put on the market, but these resins require high temperature for molding, and therefore, epoxy resins have high moldability. It is inferior to thermosetting resins such as resins. From such a background, a molding material having high heat resistance and high toughness while maintaining good moldability has been desired.

In recent years, attempts have been made to supplement the low toughness of thermosetting resins by incorporating a thermoplastic resin having relatively high heat resistance into a thermosetting resin such as an epoxy resin, and K IC is 4 kg / mm.
Some have good characteristics exceeding 3/2 . However, it cannot be said that the phase-separated structure of the molded body using these materials is necessarily homogeneous, and it is still insufficient for manifesting stable properties. Further, the prepreg for FRP, which is widely used as a structural material for sports, leisure goods and aircraft, is required to have not only heat resistance and high toughness but also workability such as tack and drape. However, depending on how the thermoplastic resin is mixed, tack and drape properties are inferior, and when tack and drape properties are imparted using a low viscosity epoxy, heat resistance and toughness tend to be inferior.

The thermosetting resin composition of the present invention is mainly controlled by the heating conditions, the radical initiator species, the radical initiator amount, the curing agent species, and the curing agent amount from the state where the respective components are uniformly mixed. The thermosetting component reacts in the thermoset molded product and is converted into a three-dimensional crosslinked product due to the combined effect of the polymerization reaction that progresses with time, spinodal decomposition type phase separation, and interaction derived from the chemical structure of each component. Both the phase and the phase composed of polyetherimide are continuous and develop a homogeneous phase separation structure in which they are finely mixed with each other. More specifically, the phase separation is suppressed to a fine level by controlling the polymerization reaction and the interaction between each component, and the cross-linking structure generated by controlling the polymerization reaction is made uniform. It is intended to make the structure homogeneous. As a result, it is possible to stably impart good characteristics having both high heat resistance and high toughness to a molded article using the composition of the present invention.

As described above, in order to impart good properties to the molded product obtained from the thermosetting resin composition of the present invention, one of the important points is to control the progress of this polymerization reaction. Is. Specifically, it is essential that the polymerization reaction of the vinyl group and the curing reaction of the epoxy group and the curing agent proceed in parallel. When the polyetherimide used in the present invention coexists, phase separation can be suppressed to a fine level by proceeding the polymerization reaction of the vinyl group and the curing reaction of the epoxy group and the curing agent in parallel. ,
If either reaction is made to precede too much, phase separation will become severe as the polymerization reaction progresses, and good characteristics cannot be obtained. Also,
By allowing the polymerization reaction of the vinyl group and the curing reaction of the epoxy group and the curing agent to proceed in parallel, cross-linking proceeds relatively quickly, so that the above phase-separated structure can be homogenized.

The bisphenol A type epoxy compound (b) used in the present invention is represented by the above structural formula (1), and is Epicoat 828 (trade name) manufactured by Yuka Shell Epoxy Co., Ltd., manufactured by Dow. D. E. R. 300, 6
00 (both are trade names) and the like are commercially available. The component (b) improves the compatibility of the components (a) and (e), facilitates the control of the phase structure by the spinodal decomposition type phase separation described above, and improves the workability by decreasing the viscosity. It also aims to improve the tack and drape of the prepreg. Various kinds of bisphenol A type epoxy compounds having different molecular weights are commercially available. Basically, it is sufficient if they are compatible with the component (a) uniformly, but if the molecular weight becomes too large, the workability is lowered and sufficient heat resistance is obtained. The problem arises that it is difficult to bring out the sex. Therefore, the component (b) preferably has a molecular weight of 1,000 or less, more preferably 500 or less. This improvement in workability can increase the added amount of the component (e), and can more effectively bring out the high toughness, which is the characteristic of the component (e). The amount of the component (b) used is preferably 10 to 90 parts by weight based on 100 parts by weight of the total amount of the components (a) and (b). Outside these ranges, the homogenization of the phase-separated structure, which is one of the features of the present invention, cannot be controlled to a fine level, and the toughness is not sufficiently imparted.
