ACRYLIC ACID POLYMERS PRODUCED BY USING SULPHUR COMPOUNDS IN THE FORM OF TRANSFER AGENTS, USE THEREOF AND AQUEOUS SUSPENSIONS CONTAINING THEM, AQUEOUS SUSPENSIONS AND COMPOSITIONS

摘要

The invention relates to polymers produced by using sulphur compounds for a method for the controlled radical polymerisation of acrylic acid and/or acrylic acid with hydrosoluble monomers in water. Said invention also relates to the use of said polymers in the form of dispersing agents or grinding aid agents and/or aid agents for combined grinding of mineral materials in an aqueous suspension or in the form of dispersing agents directly incorporated into aqueous formulations containing mineral materials. The formulations of the thus obtained mineral materials are also disclosed.
