The effect of addition of natural and precipitated chalk, unmodified and modified with stearin, on the processing and mechanical properties of polystyrene has been investigated. It has been observed that for chalk contents below 10 percent by volume the deterioration of polystyrene properties is only insignificant and that such compositions can be used fo r the manufacture of some articles. Modification of chalk has a very advantageous effect on the improvement of the properties of filled polystyrene.
