Abstract

1508134 Peptizing powdered rubbers RUBBER & PLASTICS RESEARCH ASSOCIATED OF GREAT BRITAIN 28 July 1975 [30 July 1974] 33510/75 Headings C3E and C3P Powdered rubbers are peptized by dry-blend. ing with a peptizing agent and heating the mixture to effect peptization whilst retaining the particulate nature of the powdered rubber. A partitioning agent and a filler may be included; carbon black serves both functions. Conventional peptizing agents are used, especially organic sulphur compounds. In examples, the rubbers treated are natural rubber, SBR and nitrile rubber; carbon black or whiting is present in most cases; and the peptizing agent is zinc-2- benzamidothiophenate, di - o - benzamidophenyl disulphide, zinc pentachlorothiophenate, a mixture of pentachlorothiophenol with an activator, or a chemically unidentified commercial peptizer.
