Expansible styrenic polymer.

摘要

Expandable styrene polymers containing

  a) a styrene polymer,
  b) from 0.05 to 3 % by weight, based on a), of water,
  c) from 0.001 to 1 % by weight, based on a), of a finely divided organic polymer having a water-absorption capacity of at least 10 g/g,
  d) from 0.5 to 8 % by weight, based on a), of a C3- to C6-hydrocarbon, and optionally
  e) conventional additives in effective amounts,
are distinguished by good flow properties and a low degree of clumping during prefoaming.
