Abstract

PURPOSE:To provide a caulking agent which has excellent weather resistance and does not suffer cracking during drying, containing a fatty acid-modified vinyl copolymer obtd. by subjecting a specified (beta-methyl)glycidyl group-contg. vinyl copolymer and a drying oil fatty acid to an addition reaction. CONSTITUTION:3-97wt% (beta-methyl)glycidyl group-contg. vinyl monomer such as (beta-methyl)glycidyl (meth)acrylate is reacted with 97-3wt% vinyl monomer such as styrene in the presence of a polymn. initiator such as benzoyl peroxide in a solvent to obtain a (beta-methyl)glycidyl group-contg. vinyl copolymer. 100pts.wt. said copolymer and 3-200pts.wt. drying oil fatty acid having an iodine value of 100-200, such as soybean oil fatty acid, are subjected to an addition reaction in the presence or absence of a catalyst such as imidazole at 50- 250 deg.C to obtain a caulking agent composed of a fatty acid-modified vinyl copolymer.
