Abstract

Poly(acetylene) films are produced by polymerization of acetylene, if appropriate mixed with a di- and/or poly(alkyne), in the presence of an active transition metal catalyst on filaments, fibers, woven or knitted fabrics, nonwovens, laid webs, interlaced structures or nets composed of metals, glass or natural and/or synthetic fibers.

Claims

1. A process for the production of reinforced poly(acetylene) film which comprises the following steps in sequence:

(a) impregnating a firm, fibrous, base material consisting of filaments, fibers, woven or knitted fabrics, non-wovens, laid webs, interlaced structures or nets with an active transition metal polymerization catalyst;

(b) contacting said catalyst impregnated, base material with acetylene gas or a gaseous mixture of acetylene with di- and/or a polyalkyne wherein a polymeric film of poly(acetylene) is caused to form onto, and to bond firmly with, said base material;

(c) treating the resulting reinforced, film product with a solvent to extract said polymerization catalyst therefrom, and thereafter;

(d) drying said product to remove the solvent residue therefrom.

2. A process as set forth in claim 1, wherein the base is composed of glass or natural and/or synthetic fibers and/or filaments.

3. A process as set forth in claim 1, wherein the base consists of a wire cloth.
