发明名称 POLYSILOXANE-POLYOXYALKYLENE BLOCK COPOLYMER AND STABILIZER COMPRISING SAME AND FOR PRODUCING POLYURETHANE FOAM
摘要 Polysiloxane-polyoxyalkylene block copolymers, which are intended for the production of polyurethane foams, are prepared. The foams obtained have an improved, finer cell structure and the collapse of the foams is reduced. It is essential for the invention that a mixture of polyoxyalkylene groups is present in the polysiloxane-polyoxyalkylene block copolymers. Further particulars are laid down for selecting the different polyoxyalkylene groups with regard to the respective molecular weights and the ratio of polyoxyalkylene groups to one another.
