Abstract:
A continuous process for preparing particulate microporous, open-celled polymer structures in a co-rotating twin-screw processor comprising agitating normally solid organic polymer and chlorofluorocarbon in the melt zone of said processor, cooling the resulting solution under agitation in the cooling and milling zone, extruding a snow-like mass from the cooling and milling zone, and then removing the chlorofluorocarbon from the snow-like mass to leave the polymer structures.
