| titleOfInvention | Aqueous dispersions of polymers |
| abstract | Aq. polymer dispersions (X) are prepd. by radical aq. emulsion polymerisation of a mixt. contg. at least one gp. of ethylenic unsatd. radical polymerisable monomers. The mixt. comprises 30 - 90 wt.% monomers (A) with a min. solubility of 5 wt.% in water at the chosen polymerisation temp. and pressure (w.r.t. mixt.) and 10 - 70 wt.% monomers (B) with solubility in water less than 5 wt.% under the same conditions. The mixt. contains no surfactant monomers (C). Some or all of the emulsion polymerisation takes place in a dispersant medium comprising water and an organic solvent (S) whose solubility in water is max. 10 wt.% under the above conditions. The dispersant comprises at least 20 wt.% (S) and there is sufficient (S) present to form aq. and organic phases, but the water / (S) mass ratio is not greater than 1 : 2. Also claimed are (i) the prepn. of (X) by the above method; and (ii) oil-in-water emulsions contg. (D). |
