VINYLIDENE CHLORIDE COPOLYMER AND COATING AGENT

摘要

PROBLEM TO BE SOLVED: To provide a solvent-based vinylidene chloride coating agent that is superior to the conventional vinylidene chloride coating agents in barrier properties and discoloration resistance. SOLUTION: This vinylidene chloride copolymer is produced by emulsion polymerization of a monomer mixture comprising 88-93 wt.% vinylidene chloride, 11.5-7 wt.% methacrylonitrile and 0.3-2.0 wt.% acrylic acid. A coating agent excellent in barrier properties and discoloration resistance can be produced by dissolving the vinylidene chloride copolymer and an isocyanate compound in an organic solvent.
