Title:
METHOD FOR PRODUCTION OF POLYCARBOXYLIC ACID-BASED COPOLYMER FOR CEMENT ADMIXTURE
Document Type and Number:
Japanese Patent JP2011032132
Kind Code:
A
Abstract:
To provide a method for production of a polycarboxylic acid-based copolymer for a cement admixture.
The method for production of a polycarboxylic acid-based copolymer for a cement admixture includes a process of adding a polymerization initiator dropwise to a polymerization solution.
