A powdered composition capable of being worked on heating is prepared from a PVC, or PVC copolymer, base, an/ impact resistant/ antishock additive, stabilisers and lubricants, by first mixing the additives at a temperature of 40 DEG to 120 DEG C. The mixture is allowed to cool and then dispersed in the PVC base by mixing in the cold. The mixture becomes homogeneous during the heating prior to working. |
