Als Dispergierharze geeignete Polymerisate

摘要

The invention concerns polymers (I) which are suitable as dispersing resins and are obtained by reacting: A. a polymer (II), obtained by reacting at least one compound (III) selected from the group comprising: a) an ester (IV) comprising: a1) an alpha , beta -unsaturated carboxylic acid (V), and a2) a C1-C25 alkyl alcohol (VI); b) an ester (VII) comprising: b1) vinyl alcohol, and b2) a saturated C1-C4 carboxylic acid (VIII); c) vinyl chloride; d) styrene or vinyl benzenes which carry a C1-C4 alkyl group on the benzene ring; in the presence of a compound (IX) which contains an N-oxyl radical function group; with B. at least one compound (X) comprising: a) between 50 and 100 wt %, relative to (X), of at least one compound (XI) selected from the group comprising: a1) an ester (XII) comprising: a) an alpha , beta -unsaturated carboxylic acid (XIII); and b) a C2-C10 alkyl alcohol (XIV) which carries at least one polar or acid group; a2) an amide (XV) comprising: a) an alpha , beta -unsaturated carboxylic acid (XVI); and b) ammonia or C2-C10 amine (XVII) which carries at least one polar or acid group; a3) N-vinyl compounds (XVIII); a4) styrene sulphonic acid or a vinyl benzene sulphonic acid which carries a C1-C4 alkyl group on the ring; and b) between 0 and 50 wt %, relative to (X), of at least one unsaturated ester.
