Abstract
High strength, substantially linear, highly crystalline, high molecular weight-polyolefin shaped structure having a tenacity of greater than 15 g/den and an initial modulus of greater than 500 g/den by drawing never-processed polyolefin at a temperature of 60.degree. C. to 145.degree. C.; and processes for making never-processed polyolefin and such shaped structures.
