摘要
1496543 Record composition NYNASPETROLEUM AB 8 May 1975 [10 May 1974] 19458/75 Heading G5R [Also in Division C3] Gramophone records are prepared from a preparation which comprises a vinyl halide polymer and 5 to 80% by weight of an oxidatively polymerized product having a boiling point above 350‹ C. at 760 mmHg. The said product is obtained by oxidative polymerization of a mineral oil distillate and/or a solvent extract of a mineral oil distillate, which distillate or extract has an aromatic carbon content corresponding to a viscosity gravity constant of more than 0À85. Such a product is mixed in the example with a vinyl chloride/vinyl acetate copolymer, lubricants, stabilizer and carbon black and records are moulded from the mixture.
