Process for preparing fine particles of cured polymers, and their use |
| abstract |
Pulverulent crosslinked copolymers are prepared by polymerizing monomer mixtures consisting of (a) from 70 to 99.99% by weight of monoethylenically unsaturated carboxylic acids, their amides and/or esters of such carboxylic acids and aminoalcohols, (b) from 0.001 to 10% by weight of a diethylenically or polyethylenically unsaturated monomer and (c) from 0 to 20% by weight of other monoethylenically unsaturated monomers in supercritical carbon dioxide under superatmospheric pressure in the presence of a free radical initiator. |
