Abstract: In a high concentration of chain transfer agent ethanethiol, the GC-MSanalysis of oligomers obtained by the plasma initiated polymerization of liquid monomers permits identifying and determining all compounds formed in the early propagation steps.From its analytical data the exactstructure of the starting chain end could be obtained, and allowed a more detailed description of theinitiating active species which is the ester group(这里有图片19930737-1019-1.gif) being produced by the monomer split-ted in plasma zone.

Key words: GC/MS, Plasma initiated polymerization, Active species
