摘要： The crystallinity of an amorphous precursor polycarbonate is enhanced by contact in the liquid or vapor state with a non-solvent which may be water, an alkanol or a mixture thereof and which is dialkyl carbonate-free. Contact temperatures are at least about 75.degree. C. and are further defined by the relationshipT.sub.c .gtoreq.T.sub.b -z,wherein T.sub.c is the contact temperature, T.sub.b is the boiling point of the non-solvent at the contact pressure employed (both in degrees C.) and z is a constant whose value is 60.

摘要： Solid state polymerization of polycarbonates and polyesters is preceded by a step of contacting particles of an amorphous precursor polymer with a particulate material, typically a crystallized polycarbonate, which prevents adherence of the precursor polymer particles to each other. It is then possible to perform the solid state polymerization step without crystallizing the precursor polymer.

摘要： Copolycarbonates containing such structural units as birefringence-reducing or “soft block” units are prepared by conducting a reaction, such as melt polymerization or equilibration, between a precursor polycarbonate and a monomer, polycarbonate oligomer or high molecular weight polycarbonate which is a source of other structural units. The crystallinity of the resulting precursor copolycarbonate or one of the reagents employed in its preparation is enhanced and the precursor copolycarbonate is subjected to solid state polymerization.

摘要： Amorphous precursor polycarbonates, such as oligomers, are converted to high molecular weight polycarbonates in a unitary series of operations that includes contact with an alkanol having a boiling point up to about 180.degree. C. and heating the resulting wetted particles so as to effect solid state polymerization. Heating is at progressively increasing temperatures from below the boiling point of the alkanol to a final level between the Tg and the melting temperature of said enhanced crystallinity polycarbonate.

摘要： A fluorochemical additive is the reaction product under polymerization conditions of monomers that include: (a) an aromatic polycarboxylic acid as an anhydride, ester, or ester chloride; (b) at least one fluorinated reactant; and (c) at least one aliphatic amine, mercaptan, or alcohol. Optionally, a crosslinking agent can be used. The components of the additive all can be viewed as contributing to the performance of the disclosed additive. The fluorine-containing component is generally insoluble in molten polymers and will tend to migrate to the cooled surface thereof where the fluorinated moieties provide repellency characteristics when used in adequate quantities, generally at least about 30 wt % depending on the fluorinated reactant used to make the additive. The aromatic component appears to facilitate solubility and speed up the orientation process of the additive within the molten polymer. The aliphatic component to the reaction mixture appears to assist in anchoring the reaction product additive in the bulk polymer structure. Together, the components form a fluorinated reaction product additive that can be added to a molten polymer for integration into the resulting product to impart improved resistance to oil, water, and alcohol.

摘要： The present invention discloses a vapor phase method of introducing a branching agent such as THPE into a solid polycarbonate while simultaneously crystallizing the solid polycarbonate. The partially crystalline polycarbonate containing a branching agent introduced in this manner is suitable for use in the preparation of branched polycarbonates by solid state polymerization. Branching in the polycarbonates so produced is demonstrated by rheometric measurements. Such branched polycarbonates are known to possess increased material melt strength, shear sensitivity, and complex viscosity ratio, and are particularly well-suited in blow molding applications.

The inlet passage is located as close as possible to the inlet port. A suction muffler can be located in the housing with one end connected to a second inlet in the housing and another end connected to the check valve. A discharge tube is provided between the outlet port and outlet opening in the housing.
