Abstract
PURPOSE: To obtain the titled molding excellent in light stability, dimentional stability and mechanical strength and free from surface forming, by reaction molding a specified polyol component and a polyisocyanate component in a sealed mold in the presence of a specified foam stabilizer, a blowing agent, etc.
CONSTITUTION: The titled molding is produced by reaction molding a polyol component, average OH value 480W610, consisting of 50W90pts.wt. sucrose polyether and 50W10pts.wt. polyoxyalkylene glycol of ethylenediamine and a polyisocyanate component, e.g., tolylene diisocyanate, in a sealed mold in the presence of a foam stabilizer consisting of a polysiloxane/polyoxy alkylene glycol block copolymer, average MW 10,000W20,000, represented by the formula, wherein Me is methyl, R is a 1W4C alkyl, Z is a group of formula II, X/Y is 8W15, Z content=70W80%, 1 is 0W4, m/n=2/3W1 and m+n=33W60, a blowing agent consisting of a halogen-free low-boiling solvent and a pigment.
