Abstract
A flexible film of high tensile strength and good low temperature flexibility comprises substantially linear chlorinated polyethylene having a chlorine content of 60 to 75% by weight, an intrinsic viscosity of 0.5 to 3.0 as measured in o-dichlorobenzene at 100 DEG C., and 0% crystallinity, said film being substantially unoriented and substantially free from organic solvent for said chlorinated polyethylene and having a tensile strength of at least 630 kg./cm2. The film may be obtained by chlorinating a linear high density macromolecular polyethylene having a weight average molecular weight of from 1,000,000 to 5,000,000, a crystallinity of at least 75% and a density of from 0.935 to 0.985, said macromolecular polyethylene having been produced by the gas phase polymerization of ethylene below the softening point of the polyethylene and said polyethylene containing dispersed therethrough at least 0.001% by weight of a polymerization catalyst comprising (a) chromium and (b) silica or silica-alumina. The chlorination of the polyethylene may be in two stages, the first stage being carried out in an aqueous slurry, preferably at 60 DEG to 130 DEG C. until at least 5 weight per cent of chlorine has been introduced into the polymer, and the second stage at a temperature preferably from 135 DEG to 150 DEG C. Alternatively, the second stage may be carried out in two parts, first at a temperature from 135 DEG to 150 DEG C. and then at a temperature from 110 DEG to 120 DEG C.
