Abstract
Polyester compositions based on 1,3-propanediol and aromatic and aliphatic diacids that can contain a large fraction of biologically derived content are disclosed. Transesterification between polyesters in blends of such compositions is greatly reduced using phosphorous-containing additives. The blends have properties similar to poly(ethylene terephthalate).
