Desirable properties required of curable compositions include: to have satisfactory storage stability; to give a cured product having a mat surface with almost no residual tack; to give a rubbery cured product having a low modulus and high elongation; and to give a cured product the surface of which is less apt to crack or discolor even in outdoor use. The present invention provides a curable composition which comprises: a vinyl polymer the main chain of which is a product of living radical polymerization and which contains at least one crosslinkable silyl group, and a primary and/or secondary amine having a melting point of not lower than 20°C. The curable composition of the present invention gives a cured product satisfying those properties.
                            固化组合物所需的理想特性包括:具有令人满意的贮存稳定性;固化产品具有几乎无残留粘性的哑光表面;固化产品具有低模量和高伸长率的橡胶质地;固化产品的表面即使在室外使用也不易开裂或褪色。本发明提供了一种可固化组合物,它包括:
乙烯基聚合物,其主链是活自由基聚合的产物,并含有至少一个可交联的
硅基;以及
伯胺和/或仲胺,其熔点不低于 20°C。本发明的固化组合物可提供满足上述特性的固化产品。
