ABSTRACT:
Disclosed is the preparation of micro-bits of expanded styrene-polymers and of expanded polyolefins by comminuting the styrene-polymer or polyolefin in a particular combination of comminuting steps in a suitable comminutor that can provide that combination of steps and in the presence of water as a cooling agent. The polymer micro-bits, which are produced as an aqueous slurry, may be rendered dry-to-the-touch by vacuum filtration followed by passage through a filter press.
