METHOD FOR THE PRODUCTION OF STYRENE POLYMERISATE FOAM PARTICLES.

摘要

Polystyrene foam particles having a density of 10 to 30 kg/m3 are obtained when styrene polymers containing 0.7 to 3 mol/kg of a blowing agent mixture comprising 60 to 90 mol% of water and 10 to 40 mol% of a C4- to C5-hydrocarbon are foamed using microwaves.
