| 摘要 |
The present invention relates to a dispersion comprising (i) at least one liquid polymer and (ii) at least one polymer particle mixture comprising at least one meltable solid and at least one copolymer (C), wherein said at least one copolymer (C) is a random copolymer synthesized from at least one α,&bgr;-ethylenically unsaturated monomer and at least one polymerizable polymer of the class of liquid polymers according to (i), to processes for preparing this dispersion, to the use of this dispersion to prepare polyurethanes, and to a process for preparing polyurethanes, in which at least one such dispersion is reacted with at least one polyisocyanate.
