Method of producing highly condensed polyester granulate |
摘要 |
Latent heat crystallized polyesters and copolyesters of a degree of crystallization greater than 38% and made by a process in which, without prior additive admixtures and without further cooling, the granulate is fed directly from the latent heat crystallization into a solid phase polycondensation reactor and condensed to a higher viscosity and subjected to acetaldehyde reduction. Alternatively without additive admixtures the granulate is subjected to dealdehydization and then worked up into bottles.
