摘要

A process for impregnating polymer particles, of styrene with a swelling agent, wherein the particles are intensively stirred together with a finely divided solid and a swelling agent in liquid form, at a temperature above 30º C, but below of the softening temperature of the styrene polymer, the volume ratio of swelling agent to styrene polymer being greater than 1: 1.
