Abstract

The thermoplastic constituent of a moulding composition suitable for the manufacture of gramophone records comprises a substantially petroleum-hydrocarbon-insoluble pinewood resin together with polyvinyl acetate and polyvinyl chloride. In an example, for 78 r.p.m. records, the composition of Example 2 of the parent Specification may be used except that the vinyl chloride-vinyl acetate copolymer is replaced by the same quantity of polyvinyl chloride. In a further example, suitable for the manufacture of micro-groove records, the composition consists of polyvinyl chloride 80,5 parts by weight, polyvinyl acetate 8,5, pinewood resin 7,5, dibasic lead stearate 1,0, carbon black 2,0 and carneuba wax 0,5.
