  Disclosed is a method for increasing the solid state polymerization (SSP) rates of metal catalyzed polyesters. The method comprises in a first step, reacting a dicarboxylic acid or a C 1 -C 4 dicarboxylic diester with a diol at a suitable temperature and pressure to effect esterification or transesterification to prepare a precondensate and in a second step, reacting the precondensate to effect polycondensation at a suitable temperature and pressure to prepare a high molecular weight polyester and in a third step, further increasing the molecular weight and viscosity of the polyester under SSP conditions of a suitable temperature and pressure, where a metal catalyst is added in the first step or in the second step as a reaction catalyst, and where a certain phosphinic acid compound is added in the first step, in the second step or just prior to the third step. The polyester product exhibits low aldehyde formation during melt processing steps as well as excellent color.

  本发明揭示了一种提高金属催化聚酯固态聚合(SSP)速率的方法。该方法包括以下步骤：第一步，在适宜的温度和压力下将二羧酸或C1-C4二羧酸二酯与二元醇反应，以进行酯化或转酯化反应，制备预聚物；第二步，在适宜的温度和压力下，将预聚物进行聚合反应，制备高分子量聚酯；第三步，在适宜的温度和压力下，在SSP条件下进一步提高聚酯的分子量和粘度，其中在第一步或第二步中加入金属催化剂作为反应催化剂，并在第一步、第二步或第三步前加入特定的膦酸化合物。该聚酯产品在熔融加工过程中具有低醛类物质形成以及优异的颜色。
