POWER-CONSUMING PROCESS FOR PREPARING CHEMICAL ADDITIVE TO CEMENT SYSTEMS Russian patent published in 1999 - IPC

Abstract RU 2126016 C1

FIELD: chemistry of polymers. SUBSTANCE: claimed process comprises synthesizing linear carbochain polymer by directed polymerization of calcium methylene dioxilate in the presence of initiating alkali system without outside preheating due to heat liberated during opening of smaller heterocyclic monomer ring at temperatures within 40-90 C for 20-60 min so that residual monomer concentration is equal to zero. EFFECT: substantial reduction in power capacity of claimed process. 7 cl
