MODIFIER FOR SYNTHETIC RESIN

摘要

PURPOSE:A modifier, containing a specific organopolysiloxane as a principal agent and capable of imparting good lubricity and releasability to the surface of a molded article made from a synthetic resin as well as operability. CONSTITUTION:A modifier containing an organopolysiloxane expressed by formula I [X is 2-40wt% group expressed by the formula R<1>CO- (R<1> is 7-21C monofunctional hydrocarbon) and 60-98wt% group expressed by formula II (R<2> is 7-21C monofunctional hydrocarbon; l is 1-50; q is as follows; 2<=q<=4); m is 1-50; n is 1-20; p is 1-8] as a principal agent. This modifier is used by applying to the surface of molded articles or adding to a molding resin (the amount added is 0.05-10pts.wt. based on 100pts.wt. resin).
