Abstract

The present invention provides a method for producing a modified chlorinated polyolefin-containing polymer composition excellent in production stability, and a coating material containing the modified chlorinated polyolefin-containing polymer composition. Under the coexistence of the compound (a) having allyloxy group and hydroxyl group, the chlorinated polyolefin (b) having allyloxy group and the compound selected from (meth)acrylate, (meth)acrylic acid and styrene Among them, one or more polymerizable monomers of the compound (c) are copolymerized to obtain a polymer composition containing a modified chlorinated polyolefin.

Description

technical field [0001] The present invention relates to a polymer composition containing a modified chlorinated polyolefin, a method for producing the same, and a coating composition containing the composition. Background technique [0002] Nowadays, plastic materials are used in various industrial fields. Among them, polyolefin-based resins such as polypropylene resins have many excellent properties and are economical, so they are widely used as base materials for molded articles and films. However, due to the low polarity of polyolefin-based substrates, the adhesion of the coating film formed during coating is poor. Compositions containing modified chlorinated polyolefins such as acrylic-modified chlorinated polyolefins to improve adhesion to materials and compatibility with other resin components used in combination can be used as paints or primers. [0003] Conventionally, as a method for obtaining such a modified chlorinated polyolefin-containing composition, for examp...
