    A study was made of the effect of branching and thermal history of polyethylene on its dynamic mechanical properties. The polymers used were an injection-molded linear polyethylene, with and without annealing, and an injection-molded branched polyethylene. The dynamic test apparatus was operated over a frequency range of 1(T2 to 102 cps and a temperature range of - 70 to 100 C. This temperature and frequency range includes the α and β transitions of polyethylene. These transitions are observed as peaks in the loss modulus curves.
