STUDY OF THE STRUCTURE AND PROPERTIES OF POLYCARBOXYLATE SUPERPLASTIFIER OBTAINED BY RADICAL POLYMERIZATION.
Main Article Content
Abstract
Polycarboxylate superplasticizer comb copolymers are widely used as water-reducing agents in the production of concrete products and maintain high flowability through polymer adsorption onto cement particles. Polycarboxylate copolymers with various structures are well known through free radical polymerization, but due to the high polydispersity of polycarboxylate copolymers obtained by conventional polymerization, it remains difficult to understand the relationship between structure and properties. The effects of various structural parameters still need to be studied using well-defined polymer structures.
