Abstract: Polymer (I) derived from the following monomer mixture (wt.%) is new: (A) a monomer whose homopolymer has a glass transition temperature (Tg) below 30 degrees C (45-74.9); (B) a monomer whose Tg is above 50 degrees C (25-54.9); (C) a crosslinking monomer having at least two nonconjugated vinyl groups (0.001-0.1); (D) a monomer containing acid groups (0-4); and (E) other monomer(s) (0-2). Independent claims are also included for the following: (1) a coating composition containing a binder comprising (I) produced by radical-initiated aqueous emulsion polymerization; and (2) an aqueous polymer dispersion comprising (I).

Abstract: Production of aqueous polymer dispersions (I) comprises radical-initiated aqueous emulsion polymerisation of ethylenic monomers to give a dispersion of polymer (A) followed by radical polymerisation of other monomers in one or more subsequent stages (i) in the presence of polymer (A), with the following features: (a) polymer (A) has a Tg of Tg1, (b) the monomers polymerised in stages (i) are such that the isolated statistical (co)polymerisation of these monomers gives a polymer (i) with a Tg which approaches a limiting value of Tgi with increasing molecular weight, (c) for each Tg1 the difference Tgi - Tg1 = at least 10 deg C, (d) the amount of monomers polymerised in polymer (A) is 85-99.9 wt.% of the total amount (TM) polymerised in the entire process, (e) the total amount of monomers polymerised in all stages (i) is 0.1-15 wt.% of TM, (f) in each stage (i), the addition of monomer is carried out so that monomer conversion (polymerisation) (Ui) does not exceed 50 mol% of the amount already in the reactor at any time up to the end of addition, and (g) apart from monomers with two conjugated double bonds, the total amount of monomer used for the production of polymer (A) includes not more than 5 wt.% monomers with more than one unsaturated group. Also claimed are (1) dispersions (I) obtained by this process, (2) polymer powder obtained by spray drying (I), (3) polymers obtained by this process and (4) aqueous dispersions containing such polymers.
