In order to further improve heat resistance, aromatic vinyl monomer,
Obtained by copolymerizing a vinyl cyanide monomer with an N-aromatic substituted maleimide and an aromatic vinyl monomer and a vinyl cyanide monomer in the presence of a conjugated diolefin compound. A resin composition comprising a graft copolymer has been proposed. In addition, a resin composition in which N-aromatically substituted maleimide is also blended in the graft chain of the graft copolymer is also proposed in 1). (U, S-1), :3
652'? 26). However, in the former case, as the ratio of N-aromatically substituted maleimide increases, the heat resistance id of the resulting resin composition improves, but the compatibility between the maleimide-containing copolymer and the graft copolymer deteriorates. It has the disadvantage that the folding impact resistance is reduced and the excellent properties as a rubber reinforced resin are impaired. 1. In general, graft copolymers are easy to control due to particle size, degree of gelation, and grafting rate.
The emulsion graft copolymerization method is adopted, and in order to obtain sufficient impact resistance, it is necessary to use a conjugated diolefin rubber latex with a weight average particle i of OΣμ or more.
As emulsifiers for rubber latex having such a particle size, fats and disproportionated rosins are most commonly used. Usually, the pH of rubber latex is alkaline, and graft emulsion copolymerization is performed in an alkaline atmosphere. However, when N-aromatically substituted maleimide is blended with the graft chain, the N-aromatically substituted maleimide is easily hydrolyzed in alkaline conditions and easily generates N-aromatically substituted maleamic acid or maleic acid, which is an acidic substance. Therefore, the emulsifying power of the fat or disproportionated rosin is reduced and the emulsion is easily destroyed, making it difficult to industrially produce emulsion graft polymerization. Therefore, it has been difficult to industrially obtain a graft copolymer containing an N-aromatically substituted maleimide in the graft chain and having a large effect of improving impact resistance. So N-
In order to improve the susceptibility to hydrolysis of aromatic substituted maleimide and to solve the compatibility between the small thermoplastic copolymer and the graft copolymer, conjugated zylerefine rubbers 1 to 20 were used.
A monomer mixture IC consisting of an aromatic vinyl monomer, a vinyl cyan monomer and an unsubstituted maleimide in the presence of a heavy-duty moiety
A method of polymerizing the 10iR-lit portion, ie, a one-stage grafting method that does not require mixing two types of resins, has also been proposed (Japanese Patent Laid-Open No. 47-6891). Here, as the aromatic vinyl monomer, (styrene and α-methylstyrene are mostly used, and it is preferable to increase the usage ratio of α-methylstyrene from the viewpoint of heat suppressing properties, but α-methylstyrene Since it is difficult to graft polymerize to conjugated diolefin rubber, the impact resistance cannot be improved unless α-methylstyrene is continuously added by extraction.However, unsubstituted maleimide is in powder form, and α-methylstyrene cannot be improved. It is difficult to add unsubstituted maleimide in continuous batches along with α-methylstyrene and vinyl cyanide monomer because of its poor solubility in vinyl cyanide and vinyl cyanide monomers, and add only unsubstituted maleimide separately at once. As a result, the composition distribution of the resulting copolymer becomes uneven, and the impact resistance is not improved.Therefore, it is difficult to graft α-methylstyrene to conjugated diolefin rubber, and styrene, which is easier to graft copolymerize, is must be used as a glaucoma group vinyl monomer.

However, even if the entire amount of α-methylstyrene is replaced with styrene, not only is the improvement in impact resistance insufficient, but there is also the drawback that the effect of improving heat resistance of unsubstituted maleimide is offset by the use of styrene.

The monomer composition of the thermoplastic copolymer (A) of the present invention is: aromatic vinyl monomer vinyl cyan monomer maleimide compound=30~! JO: 5-402-6.5% by weight is preferable, and 50-8010-30: 3-50 heavy stitch O stone is particularly preferable. Amount of aromatic vinyl monomer used: ○○
When the weight is less than 6A, the moldability and dimensional stability are not good.When the weight is more than 10%, the heat resistance effect does not appear, and especially in aromatic vinyl, α- When methylstyrene is used, a large amount of unreacted α-methylstyrene remains in the resin, reducing heat resistance. When the amount of vinyl cyan monomer is less than 5 weight θ, the impact resistance and oil resistance are insufficient. Further, it is necessary to use 5% by weight or more of a C.vinyl cyanide monomer that copolymerizes α-methylstyrene with a high degree of polymerization (molecular weight), high polymerization rate, and high polymerization rate. If it exceeds 40% by weight, heat resistance will decrease and coloring will occur more easily during molding of the resin.
The beauty of the product is severely damaged. If the amount of the maleimide compound used is less than 2% by weight, the effect on heat resistance will be too small, and if it exceeds 70% by weight, the copolymer will become brittle and the moldability and dimensional stability will deteriorate significantly.
