Abstract

A rubber-like material is produced by causing an oxidised drying oil such as linseed oil to react with preferably 1-14 per cent of urea, thiourea, or salts thereof, or ammonium thiocyanate. The oxidised drying oil, which may be pretreated by heating with resins such as rosin or synthetic resins, mainly of the phenolformaldehyde type, or gums such as Kauri gum, fused Congo copal gum and esterified Congo copal gum, may be in liquid form, in a dispersion in water or an organic solvent, or in the form of a solid gel, and may have been obtained from a partially polymerized drying oil. The nitrogenous compound may be added in solid form or in solution and the mixture allowed to react with or without heating. After mixing, the product may be baked at a temperature of about 100 DEG C. and may then be calendered, extruded, moulded or cured by further heat treatment. Zinc oxide, lead oxide, magnesium oxide or sulphur may also be added. Specification 332,257, [Class 70], is referred to.
