    摘要： An improved process for preparing a nitrogen or oxygen containing organoalkoxysilane such as an isocyanurate or fumarate by reacting a haloalkylaikoxysilane such as a chloropropytrimethoxysilane and a reactant of either a cyanate or an ammonium salt of an organic acid of C1-C20 carbon atoms or a metal salt of an organic acid of C1-C20 carbon atoms or mixtures thereof to a reaction temperature of at least about 80.degree. C. to about 200.degree. C., the improvement is in carrying out the reaction in the presence of a guanidinium salt phase as a transfer catalyst such as hexaethylguanidinium chloride. The improved process also is reacted wherein the temperature increase from the exotherm reaction above the reaction temperature ranges from about 0.degree. C. to about 120.degree. C. A preferred metal cyanate is sodium cyanate.

    摘要： Block copolyestercarbonates substantially free of anhydride linkages linking at least two mers of the polymer chain may be prepared by a method which comprises the steps of: (A) preparing a hydroxy-terminated polyester intermediate in a molten reaction mixture comprising at least one 1,3-dihydroxybenzene moiety and at least one aromatic dicarboxylic acid diarylester under transesterification conditions, said polyester intermediate having a degree of polymerization of at least 4; and (B) conducting a reaction of said polyester intermediate with a carbonate precursor in a two-phase system comprising an aqueous phase and a water-immiscible organic solvent. Articles comprising the copolyestercarbonates are another aspect of the invention.

    摘要： The invention relates to methods and systems for selective removal of catalyst residue from a depolymerization product stream without a water quench, as well as methods and systems for subsequent recovery of residual linear oligomer. The substantially metal-free and substantially water-free residual oligomer byproduct can then be advantageously used as recyclate in a process for preparing MPO. For example, the residual oligomer recyclate can be used as a reactant in the polymerization and subsequent depolymerization (cyclization) of low-acid polyester to form MPO.
