Increasing the efficiency of high molecular weight crosslinked polycarboxylic acids |
| abstract |
40The efficiency of high molecular weight crosslinked polycarboxylic acids which are used as thickeners for neutral and alkaline aqueous systems and are obtained by precipitation polymerization or suspension polymerization of a mixture of (a) from 70 to 99.9% by weight of monoethylenically unsaturated carboxylic acids, (b) from 0.1 to 10% by weight of ethylenically diunsaturated or polyunsaturated monomers and (c) from 0 to 20% by weight of other monoethylenically unsaturated monomers at as high as 75 DEG C. is increased by a process in which the copolymer is heated for from 2 minutes to 5 hours at from 80 DEG to 130 DEG C. after the polymerization. |
