Polyethylenes were prepared by ..gamma..-ray-induced polymerization in ethyl and n-butyl alcohols, tert-butyl alcohol containing 5 vol-percent of water, 2,2,5-trimethylhexane, 2,2,4-trimethylpentane, and cyclohexane in the temperature range 25-90/sup 0/C. The morphology of the polymers as-polymerized and studied by electron microscopy depends on three factors through the degree of undercooling: the affinity of the solvent, polymerization temperature, and the polymer molecular weight. Large lamellar crystals are formed even in the alcohols when at least two of them are chosen properly.
