Abstract

Process for the preparation of vinylarene polymer particles, which process comprises mixing a polar polymer capable of absorbing water, with vinylarene monomer, pre-polymerising vinylarene monomer;
suspending the pre-polymerised mass; and polymerise the suspended particles further. This case further relates to vinylarene polymer particles containing polar polymer and from more than 3 to 40 wt.% of water, and to foamed articles.
