Method for preparing polyoxyalkylene-organopolysiloxane copolymers |
摘要 |
A polyoxyalkylene-organopolysiloxane copolymer is prepared by reacting a polyoxyalkylene allyl ether with an organohydrogenpolysiloxane in the presence of a platinum group metal catalyst. In one embodiment, a polyoxyalkylene allyl ether having a CPR value of less than 0.5 is used. In another embodiment, a polyoxyalkylene allyl ether having a CPR value of less than 5 is used and an acid is added for neutralization prior to the reaction. The copolymer can be produced while substantially eliminating solvents and additives or minimizing the amounts thereof.
