Title:
METHOD FOR MANUFACTURING VINYL POLYMER
Document Type and Number:
Japanese Patent JP2007211048
Kind Code:
A
Abstract:

To provide a manufacturing method which prevents an acid from mixing into a vinyl polymer produced by atom transfer radical polymerization and efficiently removes transition metal.

The method for manufacturing a vinyl polymer comprises a step of bringing a vinyl polymer polymerized by the atom transfer radical polymerization of a vinyl monomer with the use of a transition metal complex as a polymerization catalyst into contact with a cation-exchange resin and a solid acid absorber to purify the polymer. The method for manufacturing a vinyl polymer comprises using a sulfonic acid type cation-exchange resin as the cation-exchange resin.
