Abstract

Gramophone records are injection moulded from compositions comprising a copolymer of vinyl chloride and vinyl acetate and 0.05 to 50% by weight of coal tar pitch. The compositions may also comprise stabilizers, e.g. lead stearate, pigments, e.g. carbon black, and lubricants, e.g. esterified montan wax, as described in Specification 1,071,331.
