DRAWN PRODUCT OF CRYSTALLINE POLYMER HAVING HIGH TENACITY AND HIGH MODULUS AND PROCESS FOR THE PRODUCTION THEREOF |
摘要 |
<p>A process for producing a drawn product of a crystalline polymer having tenacity and high modulus, which comprises compressing a gel-like material prepared from a solution of a crystalline polymer in a solvent (i.e. a gel-like sheet material (A) consisting of gel-like particles of a crystalline polymer and a solvent which is prepared by cooling a solution of a crystalline polymer in a solvent, or a gel-like film material (B) which is prepared by casting a solution of a crystalline polymer in a solvent) at a temperature lower than the temperature at which the gel-like material is dissolved, whereby removing a part of the solvent contained in the gel-like material, and drawing the compressed material, preferably using a drawing die. The drawn product is particularly useful as a tension member for optical fiber cable.</p> |
