Abstract

A composition comprising a blend of polyethylene in which the major portion of the unsaturation is branched vinyl and polyethylene in which the major proportion of the unsaturation is trans-internal and/or terminal vinyl, such as that produced in the presence of a composite chromium oxide polymerization catalyst, has improved properties such as higher softening point and better flow characteristics on extrusion. The latter type of polyethylene which has a high percentage of crystallinity, may be prepared by using a catalyst of chromium oxide admixed with silica or alumina, in a fixed bed or fluidized, at 150-450 DEG F. and relatively low pressures and purified by precipitation from methylcyclohexane. The blends may be prepared in solution, e.g. in methylcyclohexane, or by mill or Banbury mixing at a temperature of 200-275 DEG F. Examples list the properties of blends of various proportions. The compositions may be used to form sheets, films or rigid containers. Specification 790,195 is referred to.
