Abstract:
1. A polyol dispersion comprising (i) at least one polyol selected from the group consisting of polyetherols and polyesterols, (ii) at least one polymer particle mixture comprising at least one thermoplastic polymer (P) selected from the group consisting of polyesters and polyamides and copolymers of said polymers, and at least one block copolymer (B) selected from the group consisting of polyester-polyether block copolymers and polyamide-polyether block copolymers, wherein said at least one block copolymer (B) has at least one block which is compatible with said at least one thermoplastic polymer (P) and at least one block which is compatible with the polyol, wherein said at least one block copolymer (B) is in an amount of from 0.1 to 10% by weight, based on the total weight of the thermoplastic polymer (P) used, in the polymer particle mixture, and all polymer particles of said at least one polymer particle mixture comprise said at least one thermoplastic polymer (P) and said at least one block copolymer (B), and wherein the thermoplastic polymer (P) is formed prior to its addition to the polyol.
