Abstract

Copolymers of vinyl chloride or a mixture thereof with not more than 50 weight per cent of other monomers and 0.01 to 10% by weight of a divinyl ether of a C2- 20 alkanediol may be prepared by conventional processes. Specified other monomers are vinyl esters, vinyl alkyl ethers, acrylic and methacrylic esters and vinylidene chloride. Specified divinyl ethers are the ethers of ethane, propane, butane, octane, dodecane, hexadecane and octadecane diols. The polymers may be prepared by solution, emulsion or preferably suspension polymerization in the presence of a suspension stabilizer, e.g. polyvinyl alcohol, cellulose derivatives and sorbitan esters, and a catalyst, e.g. lauroyl peroxide, benzoyl peroxide, diisopropyl peroxydicarbonate and azodiisobutyronitrile. In examples vinyl chloride is copolymerized with (1 to 3) 1,12-octadecanediol divinyl ether; (4) 1,2 - ethanediol divinyl ether; (5) 1,4-butanediol divinyl ether; (6) lauryl vinyl ether and 1,12-octadecanediol divinyl ether; and (8) vinyl acetate and 1,12-octadecanediol divinyl ether in aqueous suspension in the presence of lauroyl peroxide and polyvinyl alcohol; and with (7) 1,12-octadecanediol divinyl ether in aqueous emulsion in the presence of hydrogen peroxide, sodium formaldehyde sulphoxylate and sodium dodecyl sulphate. The products are compounded with (2 and 4-7) organo tin mercaptide and lubricant; (3) dioctyl phthalate, barium stearate and tribasic lead stearate and (8) organo tin maleate. The polymers may be used as electrical insulation, e.g. wire coverings.
