Abstract
An expandable particle of a vinyl chloride resin composition for beads-foaming which comprises (A) a vinyl chloride resin composition comprising (1) a vinyl chloride resin having a difference between T.sub.1 and T.sub.2 of not higher than 45.degree. C. and (2) 1 to 30 parts by weight of an acrylic resin per 100 parts by weight of the vinyl chloride resin, (B) 2 to 40 parts by weight of an easily volatile organic blowing agent, and (C) 0 to 30 parts by weight of an organic compound capable of dissolving or swelling said vinyl chloride resin, said parts of (B) and (C) being by weight per 100 parts by weight of the vinyl chloride resin composition (A); and said T.sub.1 and T.sub.2 being measured by a Koka Shiki Flow A-method under conditions of 1 mm in nozzle diameter, 1 mm in nozzle length, 6.degree. C./minute in temperature rise rate and 100 kg/cm.sup.2 in load. The expandable particles can be easily molded by beads-foaming to foamed articles having desired complicated shapes with smooth surfaces and high expansion ratios.
