%X A new type of cross-linked capillary column coated with polyphenylenesiloxane which possesses phenylene in the siloxane main chain has been described in this paper. The cross-linking of polyphenylenesiloxane was performed in situ by the induction of DCUP. The structure of polyphenylenesiloxane is as followed: structure: see text] The repeatabilities and solvent inextractabilities of the column preparations were investigated. For decane and 1-octanol, the values of n/L and k' at 120 degrees C were 2800-3100 and 1.0-1.3, 2400-2800 and 5.0-6.0, respectively. The k' values of the columns scarcely changed after eluting with methylene chloride and pentane. The base-acid property was studied by analyzing 2,6-dimethylphenol and 2,6-dimethylaniline. Besides, in comparision with OV-17 and OV-25, the McReynolds' constants of the cross-linked column were also determined. The advantages of this kind of column are summarized as (1) easy preparation; (2) heat stability improved; and (3) good selectivity for the organic compounds which contain halogen, nitro group or phenol.
