CLAIMS

What is claimed is:

1. A bio-copolyester composition comprising: from about 92 to about 99 mole % bioPET and about 1 to about 8 mole % of biobased monomers not employed in bioPET.

DESCRIPTION

FIELD OF THE INVENTION

The present invention relates to bio-copolyesters of polyethylene terephthalate which are manufactured using 100% biobased materials, such as biobased diols or biobased acids (or their ester equivalents). Further it relates to biobased crystallization retardants and branching agents, which are copolymerized with the polyethylene terephthalate. Lastly it relates to articles formed...
