摘要： Octahydrofluorenyl metal complexes, such as octahydrofluorenyltitaniumtrichloride, or ring-substituted octahydrofluorenyl metal complexes wherein the metal is in the +2, +3 or +4 formal oxidation state are prepared by reduction of tetra- or hexahydrofluorenyl metal complexes. The reduction reaction may be carried out at ambient pressure and temperature in the presence of a catalyst. The process of the present invention permits preparation of octahydrofluorenyltitanium metal complexes from a series of high yield reactions starting with fluorene. The resulting complexes are useful as catalysts in preparing polymers having a syndiotactic stereostructure.

摘要： There are disclosed carbonate polymers having terminal arylcyclobutene moieties. Such carbonate polymers are prepared from one or more multi-hydric compounds and have an average degree of polymerization of at least 2 based on multi-hydric compound. These polymers, including blends thereof, 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.

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 2, preferably at least 3 based on multi-hydric compound. This process can be used to prepare a range of condensation polymers including polycarbonates, polyesters and polyestercarbonates. 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.
