Samples of low-density polyethylene, free from additives, were kept at temperatures between 284" and 355°C under nitrogen containing 1.16% oxygen or less. Changes in molecular weight distribution (MWD) and degree of long-chain branching (LCB) were followed by gel chromatography (GPC) and viscosity m
