EXPANDABLE STYRENE POLYMERS

摘要

An expandable styrene polymer 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 10 g/g or more, d) from 0.5 to 8% by weight, based on a), of a C3- to C6-hydrocarbon, and, if desired, e) conventional additives in effective amounts, have good flow properties and low adhesion during prefoaming.
