| titleOfInvention | Process for the preparation of aqueous polymer dispersions |
| abstract | Production of aqueous polymer dispersions (I) comprises radical-initiated aqueous emulsion polymerisation of ethylenic monomers to give a dispersion of a first polymer followed by radical polymerisation of other monomers in one or more subsequent stages (i) in the presence of the first polymer, with the following features: (a) the first polymer has a Tg of Tg1, (b) the monomers polymerised in stages (i) are such that the isolated statistical copolymerisation of these monomers gives a first polymer with a Tg which approaches a limiting value of Tg1 with increasing molecular weight, (c) for each Tgi the difference Tgi - Tg1 = at least 10 deg C, (d) the amount of monomers polymerised in the first polymer 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) does not exceed 50 mol% of the amount already in the reactor at any time up to the end of addition, (g) apart from monomers with two conjugated double bonds, the total amount of monomer polymerised in all stages (i) contains no monomers with more than one ethylenically unsaturated group, and (h) apart from monomers with two conjugated double bonds, the total amount of monomer used for the production of the first polymer includes not more than 5 wt.% monomers with more than one unsaturated group. Also claimed are (a) dispersions (I) obtained by this process; (b) polymer powder obtained by spray drying (I); (iii) polymers obtained by this process; and (iv) aqueous dispersions containing such polymers. |
