Abstract
A silicone-containing resin, film and film on a subweb are described. The resin and film are formed from (i) polyolefin, (ii) dimethyl polysiloxane having functional end-groups, (iii) vinyl silane compound, and (iv) ultra-high molecular weight silicone polymer optionally using (v) an organo-peroxide agent and (vi) an organo-metallic moisture curing agent. Resins consisting essentially of (a) functionalized polyolefins; (b) dimethyl polysiloxanes having functional end-groups to react with said functionalized polyolefins; (c) ultra-high molecular weight silicone and optional organo-metallic moisture curing agent and films or multilayer structures made therefrom are also described. The film is suitable for use in release films and in liquid-absorbing products.
