Abstract
A process for treating an acetylene polymer or a doped acetylene polymer, which comprises plasma-polymerizing a gasifiable organic compound under plasma-excitation under reduced pressure, thereby forming a polymer film on the solid surface of an acetylene polymer or a doped acetylene polymer placed in said polymerization reaction system. This process can prevent the acetylene polymer or doped acetylene polymer from being deteriorated owing to oxidation.

A process for treating an acetylene polymer or a doped acetylene polymer, which comprises:
- plasma polymerizing a gasifiable organic compound under reduced pressure by plasma excitation of said organic compound;
- and
- depositing a polymer film on a solid surface of the acetylene or doped acetylene polymer positioned in said polymerization reaction system.
A process for treating an acetylene polymer or a doped acetylene polymer, which comprises:
- plasma polymerizing a gasifiable organic compound under reduced pressure by plasma excitation of said organic compound such that the electron temperature T.sub.e and the electron density n.sub.e during the plasma polymerization obey the following relationships:
- 4. 000K.ltoreq.T.sub.e .ltoreq.80,000K and
- 10.sup.6 electrons/cm.sup.3 .ltoreq.n.sub.e .ltoreq.10.sup.11 electrons/cm.sup.3
- at a distance which is within 10 times the mean free path of the plasma molecules under pressure during plasma polymerization from the surface of the acetylene or doped acetylene polymer;
- and
- depositing a polymer film on a solid surface of the acetylene or doped acetylene polymer placed within the polymerization reaction system.
