HEAT-RESISTANT POLYMER PRODUCTION PROCESS Russian patent published in 1999 - IPC

Abstract RU 2136705 C1

FIELD: polymer production. SUBSTANCE: invention relates to production of polybenzotriazol-imides used as coatings, molding compositions, etc. Heat-resistant polymers are prepared by migration copolymerization of bis-maleimide and amine derivative in melt, which is distinguished by using, as amino derivatives, compounds of formula I (presented in description), wherein R′ is methylene, oxygen, sulfone group or ordinary bond. EFFECT: increased heat-resistance and improved physico-mechanical characteristics. 1 tbl, 2 ex
