Abstract: 863,309. Curing rubbers. B.B. CHEMICAL CO. Ltd. June 3, 1957 [June 11, 1956], No. 39646/60. Divided out of 863,308. Classes 2(6) and 70. A solid sulphur-vulcanizable rubber is cured by mixing it with a substantially infusible reaction product of PbO and a thermosetting, oil-soluble alkali-catalysed condensate of an aldehyde (more than 1 mol.) and a phenol (1 mol.) having a substituent containing at least 3 C atoms, and applying heat. The PbO-resin reaction products, prepared as described in Specification 863,308, may be milled with the rubbers in known manner to give compositions which may be moulded or extruded and which, when cured, are protected from attack by ultra-violet light and are more heat stable. In Example (3) comparative results are given of milling, moulding and curing mixtures of C black-filled rubbers with various additives, the rubbers being butadiene-styrene and -acrylonitrile copolymers, polychloroprene and natural rubber, and the additives being pphenylphenol-aldehyde resin with or without PbO and with or without stearic acid; PbO-pphenylphenol-formaldehyde reaction product with or without stearic acid; and MgO-pphenylphenol-formaldehyde reaction product.
