Abstract
Low-temperature copolymers of isoolefines with polyolefines having 4-14 carbon atoms, having an average molar weight between 25,000 and 200,000 are plasticised by milling between 200 DEG and 350 DEG F. in the presence of up to 10 per cent by weight of an alkyl mercaptan. Preferably, the mercaptan has a boiling point above 300 DEG F. and between 6 and 64 carbon atoms, specified are methyl, diisobutyl, triisobutyl, lauryl and tert.-octyl mercaptans and C16 and C18 mercaptans derived from alcohols prepared by hydrogenation of tallow, fats and oils. Isobutylene is the preferred isoolefine, polyolefines listed include butadiene, isoprene, piperylene, dimethallyl, dimethylbutadiene and myrcene. Preferably, the copolymer is prepared from a major proportion of isobutylene. The process may be carried out by a batch or a continuous method in which the copolymer is plasticised whilst passing successively through extruding and milling zones. If desired, the mercaptan may be added in solution in a hydrocarbon solvent of boiling point 325-375 DEG F. The product may be compounded, e.g. with stearic acid, zinc oxide, carbon black, sulphur and tetramethyl thiuram disulphide and cured.ALSO:Rubber-like low-temperature copolymers of iso-olefines with polyolefines having 4-14 carbon atoms (see Group IV(a)) are plasticised by milling between 200 degrees and 350 degrees F. in the presence of up to 10 per cent of an alkyl mercaptan. Preferably the mercaptan has a b.p. above 300 degrees F. and between 6 and 14 carbon atoms, specified are methyl, diisobutyl, triisobutyl, lauryl and tert. octyl mercaptans and C10 and C18 mercaptans derived from alcohols prepared by hydrogenation of tallow, fats and oils. Isobutylene is the preferred isoolefine, polyolefines listed include butadiene, isoprene, piperylene, dimethallyl, dimethyl butadiene and myrcene. Preferably, the copolymer is prepared from a major proportion of isobutylene. The process may be carried out by a batch or a continuous method in which the copolymer is plasticised whilst passing successively through extruding and milling zones.
