Abstract
An isocyanate-reactive composition comprising a first isocyanate-reactive compound and a second isocyanate-reactive compound which is normally immiscible with the first isocyanate-reactive compound and a stabilizing amount of a surfactant compound comprising a carboxylic acid ester or amide carrying a terminal acid group selected from carboxymethyl, sulphate, sulphonate, phosphate and phosphonate, provided that the methyl radical of the carboxymethyl group is not directly attached to a carbon atom of an unsubstituted hydrocarbon chain containing two or more carbon atoms.
Claims9
An isocyanate-reactive composition comprising:
- (1) a first isocyanate-reactive compound having a functionality of from 2 to 4 and an average equivalent weight of from 500 to 5000;
- (2) a second isocyanate-reactive compound which is normally immiscible with the first isocyanate-reactive compound and has a functionality of at least 2 and an average equivalent weight of from 30 to 5000;
- characterized in that it is further comprises
- (3) a stabilizing amount of a surfactant compound comprising a carboxylic acid ester or amide carrying a terminal acid group selected from the group consisting of carboxymethyl, sulphate, sulphonate, phosphate, and phosphonate, provided that the methyl radical of the carboxymethyl group is not directly attached to a carbon atom of an unsubstituted hydrocarbon chain containing two or more carbon atoms.
