  • Expandable vinyl chloride resin composition
    Patent number: 5252623
    Abstract: An expandable vinyl chloride resin composition comprising, as main components, a vinyl chloride polymer composed mainly of vinyl chloride obtained by emulsion polymerization or fine suspension polymerization of a vinyl chloride monomer and a vinyl comonomer having a hydroxyl group or a carboxyl group, a plasticizer, a chemical blowing agent and a crosslinking agent, wherein said crosslinking agent is:(1) a combination of an alkylphenol-blocked polyisocyanate and an .epsilon.-caprolactam-blocked polyisocyanate, or(2) a polyisocyanate randomly blocked by an alkyl phenol and .epsilon.-caprolactam.
