| titleOfInvention | Melt strength improvement of pet |
| abstract | Abstract of the Disclosure A composition and method for improving the thermoplastic processing characteristics of poly(ethylene terephthalate) (PET) in amorphous form are disclosed, as well as PET with improved melt strength. The composition comprises (A) a polyanhydride selected from the group consisting of pyromellitic dianhydride, mellitic trianhydride, tetrahydrofuran dianhydride, and polyanhydrides containing at least two unsubstituted or substituted phthalic anhydride radicals; and (B) a fatty acid or N-substituted fatty acid amide having at least 10 carbon atoms in the acid portion of the molecule. The polyanhydride is present in the com-position in an amount of from 0.1% to 3% by weight, based on the PET. |
