Abstract

1,163,264. Polyurethane prepolymers. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 11 May, 1967 [31 May, 1966], No. 24114/66. Heading C3R. Polyurethane prepolymers are prepared by reacting, at ambient temperature, (suitably a temperature of 0‹ to 35‹ C.), a diphenylmethane diisooyanate with a polyether diol or triol with a M.W. greater than 1000 such that the NCO: OH ratio is not less than 4:1. The prepolymers may be reacted with a polyol to form a sealant. Preferred diisooyanates are 3,3<SP>1</SP> - diphenylmethane diisocyanate; 3,4<SP>1</SP> - diphenylmethane diisocyanate and 4,4<SP>1</SP>- diphenylmethane diisocyanate (which may be the technical grade). Polypropylene glycols or polyether triols based on glycerol are preferred diols and triols. The polyol used to cure the prepolymer may be dipropylene glycol, glycerol, a polyether triol or mixtures thereof. Conventional catalysts may be used in the formation of the prepolymer and/or in the curing reaction. A filler such as china clay or a silica and/or a pigment such as titanium dioxide may be incorporated in the prepolymer or polyol or in both.
