Title:
ENHANCED NVF COPOLYMER PROCESS
Document Type and Number:
Japanese Patent JP2017025331
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a water soluble copolymer having a unimodal molecular weight distribution proved by practically one peak by a gel permeation slope elution chromatography analysis and a process of manufacturing method of the polymer.SOLUTION: There is provided a water soluble copolymer by copolymerizing N-vinylformamide of 99 to 1 mol% and one or more kind of vinyl C-Calkyl esters of 1 to 99 mol%, then hydrolyzing a formyl group from the copolymerized unit by 30 to 100 mol% to form an amino group and hydrolyzing a C-Calkylester group from the copolymerized unit by 30 to 100 mol% to form a hydroxyl group. There is provided a water soluble copolymer exhibiting a unimodal molecular weight in a gel permeation slope elution chromatography analysis.SELECTED DRAWING: Figure 1
