Publication number: 20220025174Abstract: Disclosed are polymeric compositions comprising polyhydroxyalkanoates. These compositions can comprise a blend comprising a polyhydroxyalkanoate (PHA) polymer, and a rubber polymer. The blend can comprise a biphasic mixture comprising a first phase comprising the PHA polymer, and a second phase comprising the rubber polymer dispersed with the first phase. The rubber polymer can be crosslinked, for example, through reaction with a free radical initiator. By incorporating the dynamically crosslinked rubber polymer, the polymer composition can exhibit one or more improved characteristics relative to PHA alone, including improved thermal stability, improved melt strength, improved flexibility, improved toughness, or a combination thereof. Also provided are articles formed at least in part from these polymeric compositions, as well as methods of making these polymeric compositions.Type: ApplicationFiled: December 9, 2019Publication date: January 27, 2022Inventors: Yael VODOVOTZ, Katrina CORNISH, Kurt KOELLING, Xiaoying ZHAO, Varun VENOOR

Patent number: 8013213Abstract: Transgenic guayule lines were created by constitutively expressing transgenes that encode for prenyltransferase and allylic diphosphate synthase. These new lines are important to rubber production because they result in plants that produce latex rubber which is lower in guayulin, a compound that produces a skin irritation in some animals. Controlling prenyltransferase production also permits the control of the production of resin by the plants, which has important industrial implications. Additionally, prenyltransferase manipulation can result in latex particles of different size, containing rubber of different molecular weight, which is also significant to industrial production. Although the elevated prenyltransferase activity in the transgenic lines resulted in shorter rubber molecules, the number of rubber molecules made by these transgenic lines was increased.Type: GrantFiled: November 23, 2005Date of Patent: September 6, 2011Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Christopher J. D. Mau, Katrina Cornish
