Abstract: This disclosure provide new multilayer polyester (particularly PET) containers that have improved gas barrier properties over conventional monolayer PET containers. In particular, a 2,5-furandicarboxylate polyester (for example, poly(ethylene furan-2,5-dicarboxylate) (PEF)) barrier layer that has superior gas barrier and mechanical properties relative to PET, that is “sandwiched” between two PET layers, has been found to achieve a significantly higher barrier against gas permeation relative to conventional monolayer PET container of the same size and shape. Associated preforms, methods, and compositions are disclosed.

Abstract: Disclosed are bio-based polyester fibers, particularly a PET fibers, and a method of making the same by: contacting bio-based MEG composition with a diacid composition to form a polyester composition; and spinning and/or drawing the resulting polyester composition into a fiber; wherein the bio-based MEG composition comprises: a) monoethylene glycol (MEG); and b) from about 1 ppm to about 5000 ppm of at least one C3-Cy2 1,2-diol, wherein the C3-Cj2 1, 2-diol is linear, branched, or cyclic.

Abstract: This disclosure provides effective methods for expanding the processing window for poly(ethylene furanoate) (PEF) and poly(ethylene furanoate) co-polymer (PEF co-polymer) polyester preforms, such that these preforms can be beneficially used in the fabrication of bottles and containers, including bottles for carbonated soft drinks. The processing window is expanded by, for example, pre-conditioning the PEF or PEF co-polymer preform prior to stretch blow-molding by contacting the PEF or PEF co-polymer preform with water or high (>50%) relative humidity air for a desired time period and at a temperature greater than or equal to ambient temperature, to take advantage of the unique and unexpected properties afforded the preform by water sorption at these temperatures.

Abstract: This disclosure provides an investigation of the kinetic uptake properties of water in amorphous PEF and PET across the entire water activity interval at various temperatures, and also investigates the corresponding equilibrium uptake properties at the same conditions. Uptake data were measured using three independent and complementary methodologies, and excellent agreement was observed among all three methodologies. Accordingly, this disclosure provides for methods of plasticizing poly(ethylene furanoate) film by cold water sorption, and provides a plasticized poly(ethylene furanoate) (PEF) film made according to the disclosed methods. Methods for making thin films of PEF are also provided.
