Curable compositions

Abstract

It is an object of the present invention to provide a curable composition having excellent heat resistance and weatherability and exhibiting high strength while maintaining rubber elasticity. The present invention relates to a curable composition containing a vinyl polymer (I) which has at least one crosslinkable silyl group and whose main chain is produced by living radical polymerization and a vinyl polymer (II) which has a crosslinkable silyl group and whose main chain is produced by free radical polymerization. The present invention also relates to a curable composition containing the following two components: a vinyl polymer (III) which has a crosslinkable silyl group and exhibits a glass transition temperature of less than 23° C. as determined with a differential scanning calorimeter and a vinyl polymer (IV) which has a crosslinkable silyl group and exhibits a glass transition temperature of 23° C. or more as determined with a differential scanning calorimeter.
