Abstract:
1. A process for producing an organic polymer composition which comprises Co in a content of 0.05 to 0.5 ppm, and comprised of a mixture of a reactive silicon group-containing polyether (A) and a vinyl polymer (B) which is obtained by polymerizing a vinyl monomer in the presence of a mercapto group-containing compound as a chain transfer agent, wherein in the preparation of the recited silicon group-containing polyether, the Co is present as a residue of a cobalt polymerization catalyst employed during the producing of component (A) and a purification step comprised of the following (a) is employed, wherein (a) comprises adding, to a reaction mixture containing an allyl-terminated polymer, hexane and water to extract ionic impurities into a water layer, then separating and removing the water layer, and then concentrating and subjecting the hexane layer to a volatilization under reduced pressure to yield a purified allyl-terminated polyether.
