Abstract

1351462 Recovering polymers from latices BP CHEMICALS Ltd 19 April 1971 [9 March 1970] 6105/71 Divided out of 1351461 Heading C3G Monomers other than vinyl chloride are polymerized in aqueous emulsion then in either order (a) the polymer particles are allowed to absorb vinyl chloride and (b) the polymer particles are caused to agglomerate and the agglomerates are then separated from the aqueous phase; preferably a suspension stabilizer is also added at any stage prior to separation. In examples an ABS latex formed in the presence of a rosin acid soap is mixed with vinyl chloride and in one instance polyvinyl alcohol then agglomeration is effected by adding acetic acid. The vinyl chloride is vented and the product centrifuged.
