Abstract
1,167,460. Chlorinated polyethylene. ALLIED CHEMICAL CORP. 5 Aug., 1968, No. 37275/68. Heading C3P. A chlorinated ethylene polymer, obtained from a polymer of density at least 0.9 w. gm./ cm.<SP>3</SP> and having an ethylene content of 95- 100% by weight, the remaining 0-5% consisting of propylene or a terminally unsaturated butylene, has a chlorine content of 30-37%, no detectable residual polyethylene crystallinity, an ultimate elongation between 150-500%, and an intrinsic viscosity between 2.5 and 5.5 as measured in o-dichlorobenzene at 100‹ C. The chlorinated polymer may be prepared by subjecting the polymer, of the above specified composition and a molecular weight of 250,000 -700,000, to the action of elemental chlorine in an aqueous slurry first at a temperature below the crystalline melting point of the ethylene polymer and then, while at least the last 6% of chlorine is being introduced into the polymer, at a temperature above the crystalline melting point but not above 150‹ C., and stopping the chlorination when the chlorine content is 30 to 37% by weight. The preferred temperatures are 80-120‹ C. and then 140- 150‹ C. It is preferred that the ethylene polymer is in the form of an aqueous slurry of 15-25% solids content and particle size below 20 mesh, and that the slurry contains a wetting agent. In the examples, polyethylene, prepared by polymerizing ethylene in a C 5 hydrocarbon medium in the presence of a chromium oxidesilica catalyst, or a copolymer of ethylene and butene-1, is formed into an aqueous slurry and chlorinated, the resultant polymer being extracted with water. The chlorinated polyethylene is blended with a fine particulate calcium carbonate and a liquid phthalate plasticizer.
