Abstract
1517829 Low M.Wt. polyethylene waxes PRINCETON POLYMER LABORATORIES Inc 21 July 1976 [1 Oct 1975] 30349/76 Heading C3P An ethylene polymer wax (homopolymer or copolymer containing not more than 50 mole per cent of vinylacetate, acrylic acid, methacrylic acid, maleic anhydride, or alpha-monoolefins) of number average molecular weight 1000 to 10,000, is prepared by the polymerization of the monomer(s) at 20-120 C./300- 900 p.s.i.g. in an inert or chain-transfer solvent selected from hydrocarbons, ether, carboxylic acid esters and ketones, using a free radical catalyst with a 10-hour half life at 30-60 C. In the examples, ethylene and ethylene/ propylene are polymerized using dicyclohexylperoxydicarbonate, benzoyl peroxide, t-butyl peroxypivalate, 2,4-dichlorobenzoyl peroxide and 2 – t butylazo – 2 – cyano – 4 – methoxy- 4-methylpentane, as initiators, and using as solvents hexane, benzene, tetrahydrofuran, propylene oxide, 1,3-dioxolane, ethylacetate and acetone.
