  • Patent number: 7473755
    Abstract: The present invention relates to an aromatic polyester composition for making stretch blow molded containers with improved strain hardening. The polyester composition according to the invention exhibits a low DEG content, a natural stretch ratio of <10, a half time of crystallization of >150 sec at 200° C. and comprises a sulfo-modified copolymer. Compared to polyesters of the prior art, the polyester of the present invention exhibits superior stretching characteristics, such as a lower natural stretch ratio (NSR), which allows for production of small PET bottles via thinner and longer parisons. Such thinner and longer parisons improve the production of small containers due to shorter cooling cycles.

  • Publication number: 20070160787
    Abstract: The present invention relates to a parison and container made from an aromatic polyester composition with improved strain hardening. The polyester composition exhibits a low DEG content, a natural stretch ratio of <10, a half time of crystallization of >150 sec at 200° C. and comprises a sulfo-modified copolymer. The invention further relates to a process for making small volume containers. Compared to polyesters of the prior art, the polyester of the present invention exhibits superior stretching characteristics, such as a lower natural stretch ratio (NSR), which allows for production of small PET bottles via thinner and longer pansons. Such thinner and longer pansons improve the production of small containers due shorter Cooling cycles.

  • Patent number: 6841604
    Abstract: A polyester with a carbon black content of up to 20% by weight, based on the polyester, is condensed, after transesterification of DMT with diol, or after esterification of terephthalic acid with diol, with the aid of a titanium-based catalyst. The carbon black is added in the form of a carbon black dispersion together with the polycondensation catalyst to the transesterification product or esterification product. The carbon black dispersion comprises gas black or furnace black and a dispersing agent, and these are dispersed in diol. The diameter of the carbon black particles is below that of carbon black particles in a polyester using an antimony compound as catalyst.
