  • Process for treating acetylene polymer or doped acetylene polymer
    Patent number: 4394402
    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.
