Diffusion rate of different additives was studied in ethylene polymers. The measured values were evaluated on the basis of the free-volume theory. It was concluded from the results that the rate of diffusion is primarily determined by the fractional

Because of the increase in cost of foreign oil, ethylene costs have increased markedly within the last several years. There is presently a sizeable incentive to reduce raw material costs for basic polymer manufacture. The polyketones, synthesized fro
