Abstract
A high strength and modulus conjugated polymer film which comprises as its principal constitutive unit a conjugated polymer structure represented by the general formula: --R--CH.dbd.CH.sub.n wherein R is an aromatic hydrocarbon group having 6 to 20 carbon atoms which forms a consecutive carbon to carbon conjugated system with vinylene group, and n is an integer of 5 to 50,000, and has a tensile strength of 15 kg/mm.sup.2 or more and an elastic modulus of 350 kg/mm.sup.2 or more, and a highly electroconductive pyrolyzed product thereof.

A high strength and high modulus conjugated polymer film with comprises as its principal unit a conjugated polymer structure represented by the formula:
- --R--CH.dbd.CH).sub.n
- wherein R is an aromatic hydrocarbon having 6 to 20 carbon atoms which forms a consecutive carbon to carbon conjugated system with the vinylene group, and n is an integer of 5 to 50,000;
- said conjugated polymer film has a tensile strength of 15 kg/mm.sup.2 or more and an elastic modulus of 350 kg/mm.sup.2 or more, obtained by stretch-orientating a polyelectrolyte of sulfonium salt in the form of film in the course of elimination of the sulfonium salt, and said film has a biaxial stretch ratio of 1.1 times or more, or an uniaxial stretch ratio of 3 times or more based on the size of the film of the polyelectrolyte of the sulfonium salt.
