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.
本发明涉及一种生产开环聚合产品的工艺,该工艺通过使至少一种聚异氰酸酯和 2-氧代-1,3-二氧戊环-4-羧酸反应,并在催化量的至少一种非亲核碱存在下,将反应产物置于约 40 至约 150 摄氏度的温度范围内。 得到的聚合产物可以以泡沫形式存在,适合用作粘结剂、绝缘材料、密封剂或涂层,也可用于生产床垫或伤口垫。
