摘要：The preparation of polyurethane soft foams involves using polyester polyols asthe polyol component and compound containing silicon atoms and polyether chains. -The preparation of polyurethane (PU) soft foams comprises reacting polyisocyanatescomprising isocyanate and urethane group-containing prepolymers fromdiphenylmethane diisocyanate, polyphenyl polymethylene polyisocyanates andpolyether polyols with compounds with at least two active hydrogen atoms frompolyester polyols in the presence of propellants, catalysts and additives and aidscontaining silicon atoms and polyether chains. SPECIFIC SUBSTANCES - The polyesterpolyols have a functionality of 2-4 and a mol. wt. of 1800-3600.
