Abstract: 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.
