标 题 :Method for preparing poly(vinyl trifluoroacetate) and poly(vinyl trifluoroacetate/vinyl ester) in the absence of chlorofluorocarbon solvent

权利人:MINNESOTA MINING & MFG
摘要:A method for the production of poly(vinyl trifluoroacetate) and copolymers thereof with vinyl esters is described. Poly(vinyl trifluoroacetate) (PVTFA) is obtained in essentially quantitative yield under mild conditions by using non-chlorofluorocarbon solvents comprising siloxanes or perfluorinated fluid. Hexamethyl disiloxane is a particularly useful example of such solvents. Synthesis of syndiotactic PVTFA on a commercial scale without the use of environmentally-harmful solvents is made possible by the invention, which provides a convenient commercial route to syndiotactic polyvinyl alcohol.
