modulus and process for the production thereof.
European Patent Application EP0141418 A2

ABSTRACT:
Abstract not available for EP0141418
Abstract of corresponding document: US4643865
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.
