ABSTRACT:
The compositions contain di-trimethylolpropane as a viscosity reducer in a proportion of 6 to 9 parts by weight per 100 parts of polyvinyl chloride. They advantageously contain a lead compound as primary heat stabilizer and a neutral lead carboxylate derived from C.sub.8 -C.sub.30 fatty acids as lubricant. The compositions are particularly suitable for the manufacture of rigid articles such as housings for office processing equipment and for radio and television sets and gratings for cooling towers, by injection moulding.
