| abstract | High molecular weight copolymers of ethylene and one or more mono-olefins containing not more than 6 carbon atoms and which copolymer contains 40-75 mol. per cent of units of ethylene are chlorinated to an extent of 10 to 35 weight per cent of the copolymer. The mono-olefin may be propylene, butene-1, pentene-1, hexene-1, or isopropylethylene. Exemplified copolymers are ethylene and propylene, ethylene, butene-1, and hexene-1, and ethylene, propylene, and butene-1. The copolymers are preferably made by polymerizing the monomers in the presence of an inert organic solvent or diluent and a co-ordination catalyst such as aluminium triisobutyl, or magnesium powder, and titanium tetrachloride. The chlorination is generally effected in an inert solvent such as carbon tetrachloride and a reaction initiator such as alpha-alpha1-azodiisobutyronitrile and optionally light. The chlorinated copolymers may be stabilized with epoxy compounds such as 2,21-bis-(4-glycidyloxyphenyl)-propane, and cured by compounding and heating with sulphur, a Group II metal oxide, or a rubber vulcanization accelerator such as tetraethyl thiuram disulphide, dipentamethylene thiuram tetrasulphide, 2-mercaptothiazoline, mercaptobenzothiazole, piperidinium pentamethylene dithiocarbamate, zinc diethyldithiocarbamate, or benzothiazyl disulphide. The chlorinated copolymer may also be compounded with pigments and fillers such as carbon black. The chlorinated copolymer may be used as a covering for wire, cables, and industrial rollers, or as a tank lining. Specification 497,643 is referred to. |
