CROSSLINKED DIALLYL ISOPHTHALATE/MALEIC ANHYDRIDE COPOLYMERS PRODUCTION PROCESS

摘要

FIELD: industrial organic synthesis. ^ SUBSTANCE: process, which can be applied of manufacture of plastics, resides in that diallyl isophthalate is copolymerized with maleic anhydride at their molar ratio between 1:1 and 4:1 in a unite wherein temperature of reaction mass is gradually raised from 18-20°C to 180-200°C in presence of 0.45 to 1.8 mol % of a mixture of three free-radical initiators: dicyclohexyl peroxy dicarbonate, benzoyl peroxide, and dicumyl peroxide in amounts 0.15-0.6 mol % each. ^ EFFECT: increased rupture strength of polymer, which is retained at elevated temperature. ^ 1 tbl
