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.
