Abstract: Expandable styrene polymers having a particle diameter of from 0.025 to 0.3 mm and coated with 0.5% by weight or more of a finely divided solid having a melting point above 120 DEG C. are used as a heat-insulating filler for lightweight plaster.

Abstract: The polymers consist of polystyrene, polymeric mixts. of styrene (K value 54-72 pref. 63-70) plus propane (0.05-3 pref. 0.1-0.6 wt.%) as propellant and 7-15C (pref. 7-10C) (cyclo) aliphatic hydrocarbons (0.1-7.0 pref. 0.3-6.0 wt.%) e.g. isooctane. The polymeric mixt. pref. consists of alpha-methyl styrene, (meth) acrylonitrile, 1-8C alcoholic esters of (meth) acrylic or fumaric acids N-vinyl cpds. or e.g. divinyl benzene (0.001-1.0 pref. 0.01-0.1 wt.%). The polymers are frothed by steam or heated gases deposited for 24 hrs. at room temp. compressed in a perforated form and refrothed by superheated steam through the perforations. The prod. (particle diam. 0.1-6 pref. 0.4-5mm) is used in pearl, granular etc. form, in the mfre. of polystyrene foaming plastics with reduced contraction (=1%).
