Abstract
An object of the invention is to provide a curable composition wherein the adhesiveness to thermoplastic polyolefin (TPO) is improved. The invention is a curable composition containing (A) a polyoxyalkylene polymer having reactive silicon group(s), (B) a polyolefin polymer, and (C) a tackifying resin.
Claims14
A curable composition, comprising
- (A) a polyoxyalkylene polymer having reactive silicon group(s) represented by the following general formula (1):
- —Si(R13-a)Xa (1)
- wherein R1 represents an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an aralkyl group having 7 to 20 carbon atoms, or a triorganosiloxy group represented by R3SiO— [wherein three Rs may be the same or different and are each a monovalent hydrocarbon group having 1 to 20 carbon atoms] provided that when two R1s are present, they may be the same or different, X represents a hydroxyl group or a hydrolyzable group provided that when two or more Xs are present, they may be the same or different, and “a” represents 1, 2 or 3;
- (B) a polyolefin polymer selected from the group consisting of a chlorinated polyolefin and a polymer modified with acryl, maleic acid, and/or maleic anhydride;
- and
- (C) a tackifying resin.
