摘要： Macrocyclic oligomers, including polycarbonates, polyesters, polyamides, polyimides, polyetherketones and polyethersulfones, are conveniently prepared from various spiro(bis)indane compounds, especially the 6,6'-difunctional 3,3',3'-tetramethylspiro(bis)indanes. The macrocyclic oligomers may be conveniently converted to linear polymers.

摘要： Lewis acids such as triphenyl borate, triphenylborane and aluminum isopropoxide are employed to inhibit or control the formation of linear polycarbonates from cyclic polycarbonate oligomers. Inhibition of polymerization initiated by impurities in the cyclics is noted. When polymerization is effected by basic polycarbonate formation catalysts, the Lewis acids can act as reaction rate accelerators or inhibitors depending on reaction parameters.
