Abstract

PURPOSE:To provide the titled composition having excellent flame retardance and good heat-resistance, water-resistance and punchability and composed mainly of a compounded flame-retardant polymer liquid produced by compounding a specific curable prepolymer with a specific bromine-containing flame-retardant monomer and a vinyl monomer for crosslinking. CONSTITUTION:A compounded liquid of a flame-retardant polymer is produced by compounding (A) 10-60wt.% of a curable prepolymer having (meth)acryloyl group bonded to the side chain via two urethane bonds, having a main chain consisting of a polymer obtained by a vinyl polymerization and expressed by formula I [A is main chain part of a random copolymer of a vinyl monomer and a (meth)acryloyl monomer; R is H or methyl; X1 and X2 are 2-6C hydrocarbon group or hydrocarbon group bonded by ether bond provided that the C atom bonded with O in X1 and X2 is primary or secondary], (B) 5-50wt.% of a bromine-containing flame-retardant monomer of formula II and/or III (R1-R3 are H or methyl) and (C) 5-70wt.% of a vinyl monomer for crosslinking (the sum of the components A, B and C is 100wt.%). The objective composition is obtained by using the compounded liquid as a main component.
