A paste-forming vinyl chloride polymers are manufactured by a interrupted polymerization in the presence of a conventional predisperse liquid. such as emulsifying agent, disperse acid and water, monomer and dissoluble catalyst in the monomer. The predisperse liquid is only prepared by 30-80% by weight of the required emulsifying agent and then added to the polymers. To the polymerization reactive ...

Effluent liquors, eg. those produced on cooling synthesis gas streams obtained by the ash slagging of coal in the presence of steam and oxygen, and containing volatile and oxidizable species are purified by sparging the liquor with an oxygen-containing gas. The liquor may be sparged with steam prior to oxygen-sparging or, alternatively, a mixture of steam and oxygen may be used for the sparging. T...
