Abstract
The present invention is a reactive modifier which is an acrylic polymer having a number average molecular weight of 5000 or more, obtained by copolymerizing (A) a hydrolyzable silyl group-containing monomer, (B) methyl methacrylate, (C) butyl acrylate and (D) an alkyl (meth)acrylate in which the alkyl chain has 7 to 9 carbon atoms, wherein the content of the component A is 0.01 to 10 parts by weight, the content of the component B is 5 to 95 parts by weight, the content of the component C is 5 to 95 parts by weight, the content of the component D is 5 to 95 parts by weight, the total content of the components A to D is 50 to 100 parts by weight and the weight ratio of the component C to the component D is 0.5 to 2.0. The present invention provides a reactive modifier which is inexpensive in the raw materials thereof, easy to handle and excellent in the storage stability as observed at the time of mixing with a polymer.
