    摘要： In an improved process condensation polymers having terminal arylcyclobutene moieties are prepared. Such polymers are prepared by adding to a condensation polymerization process one or more arylcyclobutene chain terminating compounds along with the multi-hydric compounds and condensation polymer precursors that are typically employed in such a process. Desirably the condensation polymers have an average degree of polymerization of at least about 2, preferably at least about 3 based on multi-hydric compound. This process can be used to prepare a range of condensation polymers including polycarbonates, polyesters and polyester-carbonates. The resulting products can be easily processed and shaped into various forms and structures according to the known techniques. During or subsequent to the processing, the polymers can be crosslinked, by exposure to heat or radiation, for example, to provide crosslinked polymer compositions. These compositions have a good combination of properties, including for example, processability into shaped articles having unexpectedly good combinations of toughness, solvent resistance, ignition resistance, modulus and resistance to thermal linear expansion.
