Title: Silane-modified polyester blends and methods of preparation

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 (R2O)2SiR3R4, wherein R2 groups are independently selected from alkyl groups containing 1-4 carbon atoms; and R3 and R4 are independently selected from OR2 groups and alkyl groups containing 1-12 carbon atoms, provided that at least one of R3 and R4 is 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.
