Abstract:
The invention relates to a process for producing a ring-opening polymerization product by reacting at least one polyisocyanate and 2-oxo-1,3-dioxolane-4-carboxylic acid and subjecting the reaction product to a temperature within the range of from about 40 to about 150° C. in the presence of a catalytic amount of at least one non-nucleophilic base. The obtained polymerization product may be present as a foam and is suitable as binder, insulation material, sealant or coating and in the production of mattresses or wound pads.

Claim (Index 4):
The process of  claim 1 , wherein the polyisocyanate is a polyisocyanate prepolymer which is obtained by reacting a molar excess of a polyisocyanate with a polyol, wherein the polyisocyanate:\n i.) is selected from an aliphatic isocyanate, an aromatic isocyanate, a cycloaliphatic isocyanate, or a combination thereof, having an \u2014NCO functionality of \u22652; and/or ii.) is selected from toluylenediisocyanate, isophorondiisocyanate, diphenylmethanediisocyanate, 4,4\u2032-diisocyanatodicyclohexylmethane, tetramethylene diisocyanate, pentamethylenediisocyanate, hexamethylenediisocyanate, isomers, dimers, trimers, oligomers and mixtures thereof.
