Abstract

Rubber, polymerization products of olefines and synthetic resins are mixed with either the extraction products of coal made by treating coal with a solvent under pressure, or high boiling fractions of hydrogenation products of coal. Synthetic resins such as polystyrene, polymethacrylic acid esters, polyvinyl esters or phenol formaldehyde condensation products are treated to form soft to hard rubber-like products. In examples, (1) to a mixture of smoked rubber sheet, zinc oxide, stearic acid, sulphur, and diphenylguanidine, there is added an extract, obtained by treating coal under elevated temperature and pressure with tetrahydronaphthalene, which acts as plasticizer or filler. The mixture is then vulcanized by heating at 127 DEG C. for \ba1/2\be hour to form a rubber composition having improved elastic properties. The coal extract may be replaced by a filtered hydrogenation residue of coal boiling about 300 DEG C. Example (3) polymerized isobutylene obtained by the process described in Specification 401,297 is intimately mixed with a coal extract as in example 1. A product similar in properties to rubber is obtained.ALSO:Rubber is mixed with either the extraction products of coal made by treating coal with a solvent under pressure, or high boiling fractions of hydrogenation products of coal.
