| description | PROBLEM TO BE SOLVED: To obtain a polyurethane foam having improved properties by using a specific block copolymer as an additive in producing the same. SOLUTION: A polyurethane foam is produced by using, as an additive, a block copolymer represented by formula I [A is R , B, E, or a group represented by formula II or III; B is a group represented by formula II or II; Y is Y or Y ; D is a group represented by formula IV R is optionally substd. 1-30C alkyl, optionally substd. aryl, or optionally substd. alkaryl provided that at least 80% of R is methyl; a is 3-200; b is 0-50; c is 0-10; and d is 0-5 provided that at least either b or C is not 0}; E is a group represented by formula V R is optionally branched alkylene; f is 0 or 1; m is on average 2-4; n is 0-100; and R is hydroxyl, optionally substd. 1-6C alkyl, acyl, or -OCONHR (wherein R is optionally substd. alkyl, aryl}; and X is a polyvalent org. group]. |
