Title:
N-ビニルホルムアミドモノマーからポリマーを製造する方法
Document Type and Number:
Japanese Patent JP4758524
Kind Code:
B2
Abstract:
The present invention is directed to precipitation polymerization processes for the manufacture of polymers prepared from N-vinyl formamide monomer, the processes including the steps of contacting the N-vinyl formamide monomer with a polymerization medium containing t-butanol as diluent and a free-radical initiator, under conditions effective to polymerize the N-vinyl formamide monomer, thereby forming a precipitate of the polymer in the polymerization medium, substantially isolating the precipitated polymer from the polymerization medium, contacting the substantially isolated polymer with a wash containing a different diluent than the t-butanol used in the polymerization and isolating the washed polymer from the wash.
