摘要： Aromatic polyesters are made in a continuous process in an extruder or extruder-like apparatus by reacting at elevated temperatures dicarboxylic acids, aliphatic esters of aromatic diols, and optionally aliphatic esters of aromatic hydroxyacids in an extruder while removing byproduct aliphatic carboxylic acid. The resulting aromatic polyesters, especially thermotropic liquid crystalline aromatic polyesters, are useful as molding resins for a variety of uses, for example electronic and electrical parts.

摘要： In an improved polymer melt cutter a gas is added to the cooling liquid before the cooling liquid enters the cutting chamber (1), or is added directly through the cutting chamber wall. This forms a cooling liquid/gas mixture in the cutting chamber, which has the advantage of providing easier startups, lower operating costs, and other advantages. Processes associated with the improved polymer melt cutter are also disclosed.

摘要： A process for producing polyamides from dinitriles and diamines in a continuous reaction using subsequent heating steps. In particular, the process involves contacting a dinitrile, a diamine, water, and optionally a catalyst to form a reaction mixture; heating the reaction mixture to a first elevated temperature of between about 180 to about 240 °C, maintaining said temperature for about 0.10 to about 20 hours, and optionally controlling the pressure in this heating step by venting; heating the reaction mixture to a second elevated temperature of between about 250 to about 350 °C, adding water to the reaction mixture before or after the second elevated temperature is reached, maintaining the pressure in the second heating step above atmospheric pressure by venting at least some of the water, and maintaining the second elevated temperature for a period of about 0.10 to about 10 hours; and recovering the polyamide.
