A reactive composition, rapidly polymerisable already starting from room temperature, comprises a liquid mixture constituted by at least one organic polyisocyanate, at least one compound containing one or more epoxy groups and a liquid catalyst constituted by, or containing, at least one compound falling within the scope of the general formula
in which the substituents have the meanings reported in the following; the compound which contains the epoxy group(s) can be constituted by the catalyst only.
Such a composition can turn into a polymeric material having softening temperatures as high as 300°C and even higher.
一种可在室温下快速聚合的反应性组合物,由至少一种有机多
异氰酸酯、至少一 种含有一个或多个环氧基团的化合物和至少一种通式范围内的化合物构成的液体混 合物组成。
其中取代基的含义见下文;含有环氧基团的化合物可以仅由催化剂构成。
这样的组合物可以制成软化温度高达 300°C 甚至更高的聚合材料。
