Abstract

PURPOSE: To obtain a closed-cell foam having improved flame retardancy, smoothness, and uniform foams, by extruding a blend of a vinyl chloride polymer and a specific aromatic vinyl polymer at a specified ratio with a blowing agent.
CONSTITUTION: (A) 10W50pts.wt. of vinyl chloride homo-or copolymer (comprising 50% or more of vinyl chloride) which is a skeleton resin is blended with (B) 90W50pts.wt. of an aromatic vinyl polymer which is polymerized in (A) to form a molding thermoplastic resin. The resin is kneaded with 2wt% based on the total resin weight of a blowing agent, e.g. n-pentane, and foam molded in an extruder to give a molded article. An antioxidant or pigment may be added, if necessary.
