Abstract
Provided are reactive silicon group-containing polymers and a curable composition containing said polymers. The curable composition provides a cured product having a low modulus, flexibility, excellent tensile strength, tensile elongation, and tear strength. The curable composition can also exhibit excellent rapid curing properties even when a low-activity catalyst has been added. In the reactive silicon group-containing polymer, a reactive silicon group, indicated by general formula (1): (—Si(R)(X)), is bonded to the molecular chain of the polymer and an atom adjacent to the reactive silicon group has an unsaturated bond. In general formula (1), each Rcan independently indicate a C1-20 hydrocarbon group, and the Rhydrocarbon groups can be substituted and a hetero-containing group can be used. X can be a hydroxyl group or a hydrolyzable group, and a is 1, 2, or 3.
