POLYMER-MODIFIED POLYOL, AND METHOD OF PREPARING THEREOF

摘要

FIELD: manufacture of polyurethane foam. SUBSTANCE: prevent invention describes olamine polymer modified polyol prepared by polymerization of olamine with polyisocyanate with isocyanate index within 55 to 90 in polyol, Number of original reagents maintains content of dry matter in stabilizer within 1 to 15 wt % so that it is used as stabilizer to prepare polymer-modified polyol. Present invention also describes method of preparing polymer-modified polyol by polymerization of olamine with polyisocyanate in polyol in the presence of added stabilizer. Stabilizer is olamine polymer-modified polyol prepared by polymerization of olamine with polyisocyanate with isocyanate index within 55 to 90 wt % in polyol, and number of original reagents maintains content of dry matter in stabilizer within 1 to 15 wt %. EFFECT: improved properties of polyurethane products, filling systems, coatings and adhesives. 12 cl, 7 ex, 3 tbl
