ABSTRACT:
Oriented polymer material of high Young's modulus and low creep strain is provided by a process which comprises drawing polymer material having a weight average molecular weight greater than 150,000 and a ratio of weight average molecular weight to number average molecular weight greater than 5 at temperatures from 95.degree. C. to 140.degree. C. and at a rate such that the deformation ratio is greater than 18.
