摘要

this invention is a back and two carboxylic acid ester to produce his reaction on polyvinyl ester polymerization process of esterification reaction and polycondensation reaction at the end of the period will be from the outside to the type (u2160) of compounds 3 ~ 6 uc911ub7c9ubd80 (u2161) compound and 0.1 ~ 0.4 weight information mixed into the polymer after polymerization by the radiation, but the trade way, dyeing processing, excellent heat resistance, excellent performance of a given event is a celebration of the characteristics is to make the ubc29ubc95uc5d0 ester fiber.;however, the period of r 1 and r u2032 carbon number 1 ~ 8, the alkyl group, and n is an integer of 1 or 2.
