PURPOSE: To provide the titled compsn. which gives cured products having excellent tensile characteristics, bond strength, weather resistance, transparency and shelf stability, consisting of a specified copolymer having a silicon-contg. functional group, an oxyalkylene polymer having a silicon-contg. functional group and a curing accelerator. n CONSTITUTION: A monomer mixture of at least 70wt% in total of 95W40wt% 1W8C alkyl (meth)acrylate (a) and 5W60wt% 10C or higher alkyl (meth)acrylate (b) is copolymerized with a compd. (c) of the formula [wherein R 4 is a (substd.) 1W20C monovalent org. group of triorganosiloxane; X is a hydrolyzable group such as OH; a is 0W2; b is 0W3; m is 0W18; R 5 is an org. residue having a polymerizable unsaturated group] to obtain a copolymer (A) having a silicon- contg. functional group and a number-average MW of 500W100,000. 100pts.wt. in total of 5W5,000pts.wt. component A and 100pts.wt. oxyalkylene polymer (B) having a silicon-contg. functional group is blended with 0.1W20pts.wt. curing accelerator (C) such as an organotin compd., an org. titanate, etc. n COPYRIGHT: (C)1988,JPO&Japio |
