Abstract
The cold-drawing of high density polyethylene has been studied over a wide range of temperatures and strain rates for a series of samples of very different molecular weight distribution. A natural draw-ratio was observed which was almost independent of temperature and strain rate, but was sensitive to the weight average molecular weight. A good correlation was observed between the Young's modulus of the drawn mono-filaments and the natural draw-ratio, and it is proposed that the Young's modulus is primarily related to molecular orientation rather than to interlamellar ties.
