Ten benzene and substituted benzene diazonium fluoroborates were synthesized and obtained in colourless crystalline form. These compounds with Mohr's salt containing small amount of copper ion as impurity were used as redox initiator for the polymerizations of acrylonitrile in aqueous solution. Rates of polymerization initiated by different substituted benzene diazonium fluoroborates were studied. Results show that the rate of polymerization with different substituents could be correlated by the Hammett...

This paper deals with the insulated treeing breakdown phenomenon in polyethylene power cables in service. It is shown that the electrical trees which develop in service may originate from impurities present in the insulation. These electrical trees (originating from impurities found in the insulation layer) grow in the direction of the electrical stress. These "impurities" are the antioxidant DNP. All these DNP, if not properly dispersed and thoroughly compatible, may act as "impurities"...

This paper deals with the insulated treeing breakdown phenomenon in polyethylene power cables in service. It is shown that the electrical trees which develop in service may originate from impurities present in the insulation. These electrical trees (originating from impurities found in the insulation layer) grow in the direction of the electrical stress. These "impurities" are the antioxidant DNP. All these DNP, if not properly dispersed and thoroughly compatible, may act as "impurities" and thus lead to gap formation and subsequent electrical treeing.

本文研究了在运行中的电力电缆的聚乙烯绝缘树枝化击穿现象,发现杂质电树枝在绝缘层中顺着电场方向成长.并指出在运行中产生的电树枝可以起源于绝缘内部存在的杂质,这些杂质就是抗氧剂DNP.所有这些DNP,如果没有适当的分散和不是充分的相容,就可以起“杂质”的作用,导致生成间隙,并接着产生电树枝化.
