Title: Molecular-weight distribution and long-chain branching of low-density polyethylene
Abstract: The molecular-weight distribution curves, indices and frequencies of long-chain branching for some samples of low-density polyethylenes were obtained. The study was based on intrinsic viscosity data of the whole polymer and on gel permeation chromatography distribution curves, both for 1,2,4-trichlorobenzene solutions at 130°C. A correlation between the index of long-chain branching and the first molecular-weight dispersion index (ratio between weight and number average molecular weights) has been postulated. Results are limited to two models for branching used in this work.
