摘要

Soln., melt or aq. dispersion of a polymer compsn. (I)which contains olefinically unsatd. bonds contains at leastone polymer (A) contg. 0.01-10(0.5-7) wt.% monomer unit(s)CH2=CR1CON(R2)CR3R4R5 (a), up to 10 wt.% monoethylenicallyunsatd. diaryl or alkylaryl ketone(s) (b) and 80-99.9 wt.%comonomers (c); and up to 10 wt.% (based on wt. of (A)) ofpolymer (B) with monomer units (b) and/or non-monoethylenicallyunsatd. diaryl and/or alkylaryl ketones; provided that (I)contains 0.01-10 (0.2-1) wt.% of units (b) + monomer units in B.
