COPOLYMERS MADE OF ISOPRENOL, MONOETHYLENICALLY UNSATURATED MONOCARBOXYLIC ACIDS AND SULPHONIC ACIDS, PROCESS FOR PRODUCING SAME AND USE OF SAME AS DEPOSIT INHIBITORS IN SYSTEMS CONVEYING WATER.

摘要

The invention relates to copolymers of (a) from 5 to 40% by weight of isoprenol, (b) from 5 to 93% by weight of at least one monoethylenically unsaturated C3 to C8 monocarboxylic acid, or of an anhydride or salt of same, (c) from 2 to 90% by weight of one or more monomers containing sulphonic acid groups.
