  Thermotropic polyesters consisting essentially of units derived from diphenols and aromatic dicarboxylic acids are prepared via monocarboxylic acid esters of the diphenols by acidolysis in two steps. The first step is a melt prepolymerization to form a prepolymer of inherent viscosity in the range of 0.12 to 0.16 dl/g-1. The second step is a melt polymerization by a single pass through a wiped film reactor, in which the film of polymer melt is subjected to a high rate of shear and to a temperature in the range within which the polyester forms an anisotropic melt phase. The polyester product has an inherent viscosity of at least about 0.5 dl/g-1.

  热致性聚酯主要由二酚和芳香族二羧酸衍生的单元组成，通过酸解二酚的单羧酸酯分两步制备。第一步是熔融预聚，形成固有粘度在 0.12 至 0.16 dl/g-1 之间的预聚物。第二步是通过擦膜反应器进行单程熔融聚合，在该反应器中，聚合物熔体薄膜受到高剪切速率和温度的作用，在此温度范围内，聚酯形成各向异性的熔体相。聚酯产品的固有粘度至少约为 0.5 dl/g-1。

  Polycarbonate granules are produced by adding a solution of polycarbonate in an organic solvent to a suspension composed of water, an anti-solvent for polycarbonate and polycarbonate powder with stirring while evaporating and removing the organic solvent for polycarbonate added to the suspension. The procedure may be effected in the presence of a stabilizing agent for polycarbonate. The resulting polycarbonate granules are easy in handling, and free from fine powder, have high bulk density, large particle size and uniform quality, and can be directly molded.
