  • Patent number: 11040170
    Abstract: Methods have been discovered that make it possible to continuously extrude tubes of P4HB and copolymers thereof. These methods allow tubes of P4HB and copolymers thereof to be produced without radial deformation of the tubes despite the slow crystallization of the polymer and copolymers. The methods can produce tubes of P4HB and copolymers thereof with tightly defined outside and inside diameters which are required for medical application. These tubes are produced by radial expansion at temperatures above the melting temperature of P4HB and copolymers thereof, and using low tube cooling temperatures and prolonged cooling times. The tubes made from P4HB and copolymers thereof are flexible, and can be prepared with high elongation to break values.

  • Patent number: 10940630
    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.
