Zusammenfassung: | Aq. polymer dispersions with a dispersed polymer content of at least 10 vol. % are claimed, contg. cpd(s). of formula (I) and/or their salts, where R = acyl gp. derived from 8-26C satd. aliphatic monocarboxylic acid, 8-26C mono- or poly-unsatd. aliphatic mono-acid or 8-26C mono-acid obtd. from the corresp. mono- or poly-unsatd. aliphatic mono-acid by partial or complete hydroxylation of the double bonds; R = OH, -O(CH2CH2O)mH (with m = 1-50), -OSO3H, -OPO2H2, an acyl gp. as above or of formula (II) where Z = -CH2CH2NMe3, OH-, -CH2CH2NH2, CH2CH2-NH-O-COR , C6H6(OH)5, -CH2CH(NH2)COOH or H); R = as for R ; R = 1-5C alkyl; in which exactly one of the gps. R and R is a gp. of formula (II). Also claimed is: (i) a process for the prodn. of these polymer dispersions by polymerising mono-unsatd. ethylenic monomer(s) by radical-initiated aq. macro-emulsion polymerisation with the addn. of cpd(s). (I) and/or their salts; (ii) aq. polymer dispersions obtd. by this process; (iii) substrates bonded, coated and/or glued with these dispersions. |
