    摘要： A process for making a thermoplastic molding composition comprising (i) forming a vertically falling stream of molten polymer, and (ii) bringing at least one additive in solid or liquid states, in solution, in the form of a dispersion or in suspension into contact with at least a part of the surface of said stream and to introduce the additive in said stream to produce combined stream, and (iii) introducing the combined stream into a pump to form a pre-mix and (iv) introducing the premix into a mixer to form a homogeneous polymer melt. The entraining stream is then introduced to a pump to form a pre-mix which is then introduced to a mixer to form a homogeneous polymer melt. The process results in a compositions having advantageous material properties.

    摘要： A multi stage process for the production of polycarbonates having low monomer content is disclosed. The process entails, in sequence, (i) transesterifying in the melt at least one dihydroxyaryl compound with at least one diaryl carbonate in the presence of at least one onium catalyst to produce a polycondensate that contains monomers, (ii) introducing into the polycondensate an inhibitor in an hypostoichiometric amount in relation to the catalyst and (iii) reducing in a finishing reactor the content of monomers in said polycondensate. The polycarbonate thus produced is characterized in that it contains less than 350 ppm of diphenyl carbonate, less than 40 ppm of 2,2-bis-(4-hydroxyphenyl)propane and less than 150 ppm of phenol.

    摘要： A continuous process for producing oligocarbonate is disclosed. The process entails in sequence the steps of a) reacting a dihydroxyaryl compound with a diaryl carbonate in the presence of a catalyst to obtain a melt and avoiding removal of released monohydroxyaryl compound and b) withdrawing the monohydroxyaryl compound by flash evaporation and c) heating the melt obtained under vacuum in an evaporator equipped with sump receiver and d) repeating at least once steps b) and then c) each at gradually increased temperatures and lowered pressures.

    摘要： A process for preparing phosphonium phenolate is disclosed. The process entails a reaction of phosphonium halide with phenol in an aqueous alkaline solution at a temperature of 0 to 55° C. The molar ratio of phenol to phosphonium halide is between 2:1 to 10:1 and the pH of the solution is 9.5 to 11. An optional embodiment entails carrying out the reaction in the further presence of alcohol.
