摘要： 在等离子体引发的液态丙烯酸酯类单体聚合体系中加入大量链转移剂乙硫醇,得到了端基带有引发活性种的低聚物,利用气相色谱-质谱的多离子检测手段,测定了活性种的结构,结果表明:引发活性种是单体在等离子体区裂解生成的酯基碎片(这里有图片19930737-1019-1.gif).进而解释了丙烯酸酯类单体可以由等离子体引发聚合,而苯乙烯不能引发聚合的问题.

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.
