Abstract

PURPOSE: To improve the resistance to deterioration, esp. resistance to hydrolysis, of a porous polyurethane sheet, useful as an artificial leather or synthetic leather, by coagulating a solution of hydrophobie polyurethane elestomer using two kinds of additives such as titanium oxide as coagulation controlling agents.
CONSTITUTION: The objective porous sheet is prepared by coagulating a solution of a hydrophobic polyurethane elastomer having a clouding value of ≤13, in the presence of (A) fine powders of titanium oxide having an average diameter of ≤3μ, pref. ≤1μ, and (B) water and/or a lower alcohol.
