Document Type and Number:

Japanese Patent JP3892226

Kind Code:

B2

Abstract:

An expandable vinyl chloride resin composition in which the expansion ratio for the vinyl chloride resin can be significantly heightened by using a thermally decomposable inorganic foaming agent in place of an organic solvent foaming agent. The composition comprises 100 parts by weight of a vinyl chloride resin, 5 to 30 parts by weight of a (meth)acrylic ester polymer, as a processing aid, whose solution in chloroform with a concentration of 0.1 g/100 ml has a specific viscosity at 30 DEG C of 0.73 or higher, and 2 to 25 parts by weight of a thermally decomposable inorganic foaming agent.
