Abstract
Provided are: a method for producing a polymer composition containing a modified chlorinated polyolefin, which exhibits excellent production stability; and a coating material which contains a polymer composition containing a modified chlorinated polyolefin. According to the present invention, a polymer composition containing a modified chlorinated polyolefin is obtained by copolymerizing polymerizable monomers including (b) a chlorinated polyolefin having an allyloxy group and (c) one or more compounds selected from among (meth)acrylic acid esters, (meth)acrylic acids and styrene in the coexistence of (a) a compound having an allyloxy group and a hydroxyl group.

A method for producing a polymer composition containing a modified chlorinated polyolefin, the method including a step of copolymerizing a chlorinated polyolefin that has an allyloxy group (b), and a polymerizable monomer including one or more compounds (c) selected from the group consisting of (meth)acrylic acid esters, (meth)acrylic acid and styrene, in the co-presence of a compound that has an allyloxy group and a hydroxyl group (a), to obtain a modified chlorinated polyolefin,
- wherein the compound that has an allyloxy group and a hydroxyl group (a) is a compound represented by the following formula (I):
- wherein R1 and R2 each independently represent an alkylene group of 2 or 3 carbon atoms that is optionally branched, m and n each independently represent a real number of 0 to 50, the sum of m and n being a real number of 1 or greater, and the structure may be a block structure or random structure.
