A process for producing a drawn product of a crystalline polymer having high 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 solventl at a temperature lowerthan 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.
一种生产具有高韧性和高模量的结晶聚合物拉伸产品的工艺,包括压缩由结晶聚合物在溶剂中的溶液制备的凝胶状材料(即凝胶状片材 (A),由结晶聚合物的凝胶状颗粒和溶剂组成,通过冷却结晶聚合物在溶剂中的溶液制备;或凝胶状薄膜材料 (B),通过在低于凝胶状材料溶解温度的温度下浇铸结晶聚合物在溶剂中的溶液制备,从而除去凝胶状材料中所含的部分溶剂。拉伸后的产品特别适用于光缆的拉伸件。
