Abstract: 1,228,921. Chlorinating ethylene polymers. BADISCHE ANILIN- & SODA-FABRIK A.G. 28 Aug., 1968 [29 Aug., 1967], No. 41123/68. Heading C3P. A chlorinated ethylene polymer is prepared by allowing gaseous chlorine to act on a finely particled compact ethylene polymer which has been obtained by high pressure polymerization and which has an average particle diameter with the range from 200 to 800 microns and a specific surface area of from 70 to 300 cm. 2 /g. in the absence of solvents and suspension agents. Suitable polymers are homopolymers of ethylene or copolymers of ethylene with one or more other singly unsaturated olefins e.g. propylene or n-butene. The ethylene polymer may have a molecular weight of 10,000 to 180,000 and a density of 0À880 to 0.938 g./cm. 3 . The chlorination may be carried out in a fluidized bed, a rotary kiln or a stirred vessel.
