    摘要: Copolyetherimides comprise phthalimide structural units comprising both 3- and 4-linkages, wherein the designations 3-linkage and 4-linkage refer to the isomeric positions on the phthalimide ring in the totality of phthalimide-comprising structural units in the copolymer. The products have excellent properties, including high glass transition and heat distortion temperatures, high ductility and good melt flow properties, and low polydispersity.

    摘要: Polyether polymers, such as polyetherimides, are prepared by the reaction of a dihydroxy-substituted aromatic hydrocarbon alkali metal salt, such as bisphenol A disodium salt, with a bis(N-(chlorophthalimido))aromatic compound, such as 1,3- and/or 1,4-bis(N-(4-chlorophthalimido))benzene, in a solvent such as o-dichlorobenzene and in the presence of a phase transfer catalyst such as a hexaalkylguanidinium chloride. Several embodiments may be employed to improve the method. They comprise employing substantially dry reagents, employing a high solids level in solvent, beginning with an excess of bis(N-(chlorophthalimido))-aromatic compound and incrementally adding alkali metal salt, employing alkali metal salt of small particle size, and using reagents of high purity.

    摘要: High heat polyethersulfone compositions are provided which possess unexpectedly high glass transition temperatures. The polyethersulfone compositions comprise structural units derived from phthalimide bisphenols such as 3,3-bis(4 -hydroxyphenyl)-N-phenylphthalimide, and structural units derived from at least one biphenyl-bissulfone such as 4,4′-bis((4-chlorophenyl)sulfonyl)-1,1′-biphenyl. The novel polyethersulfone compositions may further comprise structural units derived from one or more biphenols such as 4,4′-biphenol, bisphenols such as BPA, or other electrophilic sulfone monomers, such as bis(4-chlorophenyl)sulfone. In one embodiment, the polyethersulfone composition of the present invention comprises structural groups derived exclusively from 3,3-bis(4-hydroxyphenyl)-N-phenylphthalimide, and 4,4′-bis((4-chlorophenyl)sulfonyl)-1,1′-biphenyl and exhibits a single glass transition of greater than 300° C.
