Title:
PREPARATION OF WATER-SOLUBLE HIGH POLYMER HAVING HIGH POLYMERIZATION DEGREE
Document Type and Number:
Japanese Patent JPS5827702
Kind Code:
A
Abstract:
PURPOSE: To obtain the titled substance suitable for flocculants, yield increasing agents, viscosity increasing agents, etc., by reacting an acrylaminde water- soluble high polymer with an aliphatic dialdehyde, and joining them in a specific range.
CONSTITUTION: One or more aliphatic dialdehydes, e.g. malonaldehyde, of the formula OHC-R-CHO (R is alkylene or alkenyl), are reacted with an aqueous solution of an acrylamide water-soluble high polymer, e.g. polyacrylamide, in a concentration of preferably 0.5W10%, and the raw material high polymer is mutually joined in such a range as to keep the formed high polymer water soluble.
