POLYMERIC POLYOLS AND POLYMER DISPERSIONS OBTAINED FROM HYDROXYL-CONTAINING MATERIALS BASED ON VEGETABLE OIL

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to polymeric polyols obtained from hydroxyl-containing materials, as well as dispersions of polymer particles in the said material. The polyol has a continuous polyol phase and dispersion ethylene-unsaturated polymer particles grafted on at least one stabiliser. The polyol phase contains at least one hydroxymethyl-containing polyester polyol derived from a fatty acid or a fatty acid ester. The polyol is a product of reaction between 9(10)-hydroxymethyl stearate or its alkyl ester and polyether polyol, containing ethylene oxide or propylene oxide links. The dispersion particles are a vinylaromatic polymer, nitirle with ethylene unsaturation or a mixture of two or more of them. The stabiliser is an addition compound of polyether polyol and vinylmethoxy silane or isocyanate with ethylene unsaturation. ^ EFFECT: invention enables to obtain stable polymeric polyols with low viscosity and high strength. ^ 33 cl, 4 tbl, 12 ex
