Abstract
A silane-modified polyester blend comprising a polyester polymer homogeneously blended with silane molecules containing two or three alkoxy groups bound to the silicon atom, wherein said silane molecules are present in said polyester blend in an amount of 0.05-20 wt % (or, e.g., 0.05-10 wt %, 0.05-5 wt %, or 0.05-2 wt %). The polyester polymer may, in particular embodiments, be a polyhydroxyalkanoate, terephthalate-based polyester, adipate-based, or succinate-based polyester. The silane molecule may be according to the formula (RO)SiRR, wherein Rgroups are independently selected from alkyl groups containing 1-4 carbon atoms; and Rand Rare independently selected from ORgroups and alkyl groups containing 1-12 carbon atoms, provided that at least one of Rand Ris an alkyl group, wherein the alkyl group optionally includes one or more heteroatoms selected from oxygen, nitrogen, halogen, sulfur, phosphorus, and silicon. Methods for producing the silane-modified polyester blend are also described.
