摘要： PURPOSE: Provided are a transparent heat resistant resin containing reduced residual maleimide monomers, emitting reduced maleimide monomers by heat in a molding process or the like, excellent in heat resistance and hardly causing discoloration, and its manufacturing method and a resin composition using the same. CONSTITUTION: The transparent, heat resistant resin is obtained by polymerizing a co-monomer component containing a maleimide monomer and a methacrylate monomer. When the content of structure units derived from maleimide monomers in the resin is X wt.%, the resin contains residual maleimide monomers of 10X ppm or less and emits 10X ppm or less of maleimide monomers when heated for 10 min at 240deg.C. In a method of obtaining a transparent, heat resistant resin by polymerizing a co-monomer component containing a maleimide monomer and a methacrylate monomer, an acidic substance is caused to be present along with a sulfur-containing chain transfer agent in the reaction system in polymerization.

摘要： The present invention provides: a transparent heat-resistant resin that has a small amount of both the residual maleimide monomer and the maleimide monomer generated by heating in order to carry out such as a mold processing, and further, is excellent in heat resistance and yellowish little; a production process therefor; and a resin composition utilizing this resin. The transparent heat-resistant resin, according to the present invention, is obtained by a process including the step of running a polymerization of comonomers including a maleimide monomer and a methacrylic acid ester monomer, wherein the amount of the residual maleimide monomer in the resin is not more than 10X ppm when the amount of a structural unit derived from the maleimide monomer is X weight % in the resin, and the amount of the generated maleimide monomer by heating the resin at 240 DEG C for 10 minutes is not more than 10X ppm when the amount of a structural unit derived from the maleimide monomer is X weight % in the resin. In addition, the production process for a transparent heat-resistant resin, according to the present invention, comprises the step of running a polymerization of comonomers including a maleimide monomer and a methacrylic acid ester monomer in order to obtain a transparent resin having heat resistance, wherein an acidic substance is made to exist with a sulfur chain-transfer agent in the polymerization system during the polymerization.
