Abstract

Homopolymers or copolymers are produced by radical polymerisation in an aqueous phase at 273 DEG to 373 DEG K, the aqueous phase being a solution or dispersion containing at least one monomer chosen from vinyl halides, vinyl esters, vinyl ethers, vinylidene halides, acrylic and methacrylic monomers and ethylenically unsaturated bicarboxylic acids and their esters, by maintaining a monomer or total monomer concentration corresponding to the solubility of the or each monomer in the aqueous solution or dispersion, the partial vapour pressure of the or each monomer being maintained below the respective partial saturation vapour pressure of the respective monomer. Preferably at least one of the monomers is a vinyl monomer. Advantageously the aqueous phase contains at least one additive chosen from specified hydrocarbons and esters.
