    摘要: Benzocyclobutene-terminated monomers of the formula ##STR1## wherein Ar is --SO.sub.2 --, --CO--, or ##STR2## are prepared by reacting a benzocyclobutene of the formula ##STR3## wherein R is --H or --SiMe.sub.3, with a difluorophenyl compound of the formula ##STR4## wherein Ar is as described previously, in the presence of a promoter. A mixture of the resins is obtained when potassium carbonate is employed as the promoter. The bis(benzocyclobutene)-terminated monomer is obtained when cesium fluoride is employed as the promoter.

    摘要: Novel ether-ketone-imide hyperbranched polymers with thermally reactive ethynyl endgroups were prepared from the corresponding AB2 monomer and the respective benzophenone-based endcapping agents in one-pot fashion. The resulting polymer has repeating units of the formula: where the chain-end groups, Ar is a benzophenone with an ortho, a meta- or a para-ethynyl substituent.

    摘要: A new benzidine monomer composition containing an asymmetrically situated benzamide (iminobenzoyl) group: ##STR1## was prepared from the benzolyation reaction of 4,4'-dinitro-2-biphenylamine and benzoyl chloride, followed by catalytic hydrogenation. The compound can be used as a comonomer in the preparation of soluble thermoplastic polyamides, polyimides and other high performance polymers whose preparations require a diamine monomer.
