Abstract
PURPOSE: To obtain an open-cell foam having improved air permeability moisture permeability, and water permeability, blending a vinyl chloride resin composition with a specific blowing agent and an anionic surface active agent, forming the blend into a sheet, expanding it under heating.
CONSTITUTION: (A) A vinyl chloride resin composition obtained by blending (i) a vinyl chloride resin with (ii) 60W100PHR plasticizer, e.g., phthalic ester, etc. and (iii) ≤50PHR filter, e.g., calcium carbonate, etc. (an average particle diameter preferably 2W20μ) is blended with (B) 4,4'-oxybis(benzene hydrazide) as a flowing agnet and (C) an anionic surface active agent (preferably alkylsulfuric ester, etc.) under heating. The blend is rolled simultaneously with the topping of a backer to give an unfoamed leather, which is expanded under heating to give the desired material. A lubricant is preferably added to prevent the adhesion of the blend to rolls.
