摘要： This invention relates to an extrusion method preparing polycarbonates from a solution of an oligomeric polycarbonate. A mixture of bis(methyl salicyl)carbonate (BMSC), BPA and a transesterification catalyst are first equilibrated at moderate temperatures to provide a solution of polycarbonate oligomer in methyl salicylate. The solution is then fed to a devolatilizing extruder, where the polymerization reaction is completed and the methyl salicylate solvent is removed. The solution comprising the oligomeric polycarbonate can also be pre-heated under pressure to a temperature above the boiling point of methyl salicylate and subsequently fed to a devolatilizing extruder equipped for rapid flashing off the solvent. The method provides polycarbonate with greater efficiency than the corresponding process in which unreacted monomers are fed to the extruder. Additionally, the method of the invention does not require the isolation of a precursor polycarbonate comprising ester-substituted phenoxy terminal groups.

摘要： Extrusion of a mixture of an ester-substituted diaryl carbonate, such as bis(methyl salicyl) carbonate, a dihydroxy aromatic compound such as bisphenol A and a transesterification catalyst such as tetrabutylphosphonium acetate (TBPA) affords polycarbonate having a weight average molecular weight of greater than 20,000 daltons. The extruder is equipped with one or more vacuum vents to remove by-product ester-substituted phenol. Similarly, a precursor polycarbonate having ester-substituted phenoxy endgroups, for example methyl salicyl endgroups, when subjected to extrusion affords a polycarbonate having a significantly increased molecular weight relative to the precursor polycarbonate. The reaction to form a higher molecular weight polycarbonate may be catalyzed by residual transesterification catalyst present in the precursor polycarbonate, or by a combination of any residual catalyst and an additional catalyst such as TBPA introduced in the extrusion step. Fries rearrangement products are not observed in the product polycarbonates.

摘要： High levels of silica, processing fluid and high molecular weight silicone polymer are compounded into a homogeneous silica filled composition without forming a preconcentrate of fumed silica and polymer. A fumed silica is fed into a unitary continuous compounding apparatus at a first location prior to addition of the silicone polymer. The fumed silica is then compounded with the silicone polymer, which is fed into the compounding apparatus at a location down-stream in the compounding apparatus from the first location. The compounding apparatus can be a co-rotating, intermeshing double screw extruder.

摘要： A method for preparing a polyimide includes introducing a mixture of an oligomer and a solvent to an extruder, removing solvent via at least one extruder vent, and melt kneading the oligomer to form a polyimide. The polyimide has a low residual solvent content. The method is faster than solution polymerization of polyimides, and it avoids the stoichiometric inaccuracies associated with reactive extrusion processes that use monomers as starting materials.
