摘要:
Heat-expandable microspheres containing a thermoplastic resin shell and a thermally-vaporizable blowing agent encapsulated therein. The thermoplastic resin is a polymer of a polymerizable component containing acrylonitrile, methacrylonitrile and acrylate ester and which satisfies specific conditions 1 and 2, where Condition 1: the amount of the acrylonitrile (A)
