PURPOSE: To provide a composition having remarkably improved adhesivity to various adherends and weather resistance, by compounding a polyether containing a reactive silicone functional group in the molecule with a vinyl polymer containing a reactive silicone functional group in the molecule. n CONSTITUTION: The objective composition is prepared by compounding (A) 100pts.wt. of a polyether containing at least one reactive silicone functional group in a molecule with (B) 0.1W1,000pts.wt. of a vinyl polymer containing at least one reactive silicone functional group in one molecule. The component (A) is preferably an oxyalkylene polymer having a molecular weight of 500W30,000 and having a main chain composed of the group of formula -R 5 -O- (R 5 is 1W4C bivalent alkylene). The component (B) is the one obtained by the copolymerization of a vinyl monomer of formula (R 1 is H, halogen, etc.; R 2 is R 1 or 1W20C univalent organic group) and a silicone compound containing carbon double bond and hydrolyzable group. n COPYRIGHT: (C)1984,JPO&Japio |
