Abstract

Cellular prods. are prepd. by sintering and moulding expansible particlese contg. (I) a styrene polymer, (II) an ethylene polymer, (III) a homogeniser, and (IV) a blowing agent. Mouldings with a complicated shape that accurately corresponds to the mould cavity can be easily obtained, having good impact resistance at low temps. and resistance to solvents.
