A polymer dispersed polyol has a vinyl polymer dispersed in polyol, the vinyl polymer comprising containing 5 to 80 wt% of acrylamide compound (A) represented by the formula (1):
CH2=CR1CONR2R3 (1)
wherein R1, R2 and R3 are a hydrogen atom or hydrocarbon group having 1 to 10 carbon atoms, 0 to 70 wt% of one or more monomer (B) selected from acrylonitrile and methacrylonitrile, and 0 to 95 wt% of a vinyl monomer (C) which can copolymerize with (A) and (B), and 95 to 20 wt% of the total amount of (B) and (C); and when (C) is 0 wt%, (A) is the polymer of a vinyl monomer mixture containing an acrylamide derivative represented by the formula (2):
CH2=CR4CONR5R6 (2)
wherein R4, R5 and R6 are a hydrogen atom or hydrocarbon group having 1 to 10 carbon atoms, and not simultaneously the hydrogen atom; and said polyol comprising containing 5 to 50 wt% of the vinyl polymer. Flame retardant polyurethane resins and flame retardant polyurethane foams are obtainable from the polymer dispersed polyol.
