「POLYIMILEXTM」
Maleimide copolymer“POLYIMILEXTM” is the copolymer that has been developed by using maleimide (Imilex-P) which was
first commercialized by Nippon Shokubai.
PolyimilexTM is effective in enhancing heat resistance by compounding PolyimilexTM with various
thermoplastic resins. PolyimilexTM is expected to be used for developing new applications as raw materialfor new polymer alloys.

Features
Heat resistance ： Effective in enhancing heat resistance of various thermoplastic resins
Low impurities ： PolyimilexTM contains very low impurities because of using purified maleimide bydistillation as raw materials
