Compositions of compatibilized blends of polyamides in polyesters, methods and resins for forming such compositions, and containers made from such compositions which higher burst pressure, crystallization at higher temperatures during production and reduced haze as compared to than containers made from previous blends are disclosed.

Polyethylene terephthalate containers with improved performance

The present disclosure relates to masterbatch compositions used for preparing articles, preforms or containers comprising a base polyester, a transition metal-based oxidation catalyst, an alkali metal compound, and an alkaline earth metal compound. The masterbatch compositions have desirable viscosity characteristics and the prepared articles, preforms or containers using these masterbatch compositions have desirable mechanical, visual and gas barrier properties.

Polyester-ether resin blends

The present application relates to novel polyester-ether compositions and their use as oxygen scavenging materials in polyester resins.

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 &#x3c;10, a half time of crystallization of &#x3e;150 sec at 200&#xb0; 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.

Aromatic polyester composition for making stretch blow molded containers

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.
