    摘要: The invention provides methods and formulations involving the use of promoters that accelerate the polymerization of macrocyclic polyester oligomers (MPOs). For example, in certain embodiments, the invention provides blends of macrocyclic polyester oligomer (MPO), catalyst, and promoter that are substantially stable at ambient temperature for a period of time. The blend material may be stored without premature polymerization of MPO or deactivation of catalyst. The invention also provides processes employing one-part, ready-to-polymerize blends that contain MPO, catalyst, and promoter, as well as processes in which the catalyst and promoter are used in separate streams and are contacted when it is desired to accelerate polymerization of MPO. Methods of the invention offer advantages in the manufacture of thermoplastic parts and composites, due at least in part to the unique properties of MPO.

    摘要: The invention provides intimate physical mixtures of macrocyclic polyester oligomer (MPO) and filler, as well as methods for their preparation and use. Improved dispersion of filler in a polymer matrix is achieved upon polymerization, and larger amounts of filler with high aspect ratio can be used. In one aspect, the invention provides mixtures of MPO with magnesium silicate. In another aspect, the invention provides a mixture of MPO, filler, and polymerization catalyst as a one-part, ready-to-polymerize material with a long shelf life. The one-part material can be used, for example, in the manufacture of parts without modification of existing processing equipment.

    摘要: Copolymers of polycarbonates or polyarylates with polyether polymers such as polyethersulfones, polyetherketones, and polyetherimides are prepared by reaction of the polyether polymer-forming reagents, e.g., bisphenol A disodium salt and bis(4-chlorophenyl) sulfone, in the presence of the polycarbonate or polyarylate. The reaction may take place in a dipolar aprotic solvent, or in a water-immiscible aromatic solvent in the presence of a phase transfer catalyst, preferably a hexaalkylguanidinium halide. Hydroxy-terminated polyether oligomers may be produced from the copolymers by saponification of carbonate or ester groups.
