CURABLE SEALANT COMPOSITION AND METHOD FOR MANUFACTURING SAME

摘要

In one embodiment of the present invention, a curable sealant composition and method for its preparation are provided. The composition includes a polymer which is prepared by functionalizing a poly(conjugated diene) with a curable group such as tetra-substituted silicon compound and then substantially hydrogenating the functionalized polymer in the presence of 2-jegler type catalyst. The composition can further include additional curable sealant ingredien selected from the group consisting of plasticizers, fillers, reinforcing agents, modifiers, curing catalysts/hardeners, stabilizers, and mixtures thereof.
