Title:
【発明の名称】N-(置換)マレイミド類およびそれらを組み込んだ組成物
Document Type and Number:
Japanese Patent JPH08506133
Kind Code:
A
Abstract:
Novel resin compositions are provided which possess excellent heat resistance and thermal color stability, alone, or in admixture with bulk resins. The claimed resin compositions comprise homo- and/or copolymers of N-(2,3-dimethylphenyl) maleimide, alone, or in further combination with resins composed of copolymer components, such as vinyl copolymers and rubber-grafted vinyl copolymer resins. The resin compositions have improved heat resistance and produce molded articles with desirably light colors. Also provided is an improved process to make maleimide monomers by using selected polar solvents whereby the amount of uncyclizable trans-amic acid is held at tolerable levels and the desired maleimide is obtained in high yields, free from by-products.
