Abstract: Aq. polymer dispersions (I) are claimed, contg. polymer(s) obtd. by radical polymerisation (II) and (w.r.t. polymer(s)) (a) 0.5-3 wt.% polyether(s) derived from ethylene and propylene oxide (EO and PO), (b) 0.5-4 wt% ethoxylated alkylphenol(s) and/or ethoxylated fatty alcohol(s), (c) 0.5-3 wt% ethoxylated polysaccharide(s) and (d) 0-4 wt% sulphate half-ester(s) of ethoxylates (b) or water-soluble salts thereof (dispersants a, b, c and d). Also claimed is a process for producing (I) by radical aq. emulsion polymerisation of a mixt. of monomers in the presence of a radical initiator and dispersant mixt. (1-d).

Abstract: Aq. polymer dispersions (I) are claimed. (I) are obtd. by aq. emulsion polymerisation of a mixt. of (a) 50-80 wt.% vinyl 1-18C alkanoate(s) (unbranched), (b) 5-40 wt.% vinyl 1-20C alkanoate(s) (branched), (c) 0-45 wt.% 1-18C alkyl ester(s) of 2-6C alpha, beta-mono-unsatd. carboxylic acid and (d) 0-5 wt.% other comonomers, in the presence of dispersants (II) and radical initiators (III). (II) comprises (A) 0.5-3 wt.% polyether(s) derived from ethylene oxide (EO) and propylene oxide (PO), (B) 0.5-4 wt.% ethoxylated alkylphenol(s), (C) 0.5-3 wt.% ethoxylated polysaccharide(s) and (D) 0-4 wt.% sulphate half-ester(s) of ethoxylated alkylphenols and/or water soluble salts thereof (% w.r.t. monomer mixt.). USE/ADVANTAGE - Used in aq. or spray-dried form as additives for mineral constructional binders, esp. based on cement (claimed). Also claimed are mineral binders contg. polymer powder obtd. by spray drying (I).
