Abstract: Stereocomplex biopolymer compositions having tunable and improved mechanical properties and methods of making such compositions are disclosed. The biopolymer compositions include combinations of a matrix-forming polylactic acid comprising an essentially pure enantiomer and a tough polyester to form a polylactic acid matrix. The polylactic acid matrix is further combined with a base polylactic acid comprising an essentially pure opposite enantiomer of the first essentially pure enantiomer of the matrix-forming polylactic acid to form the stereocomplex.

Abstract: L-Polylactic acid and D-Polylactic acid biodegradable biopolymers are combined with torrefied biomass and a plasticizer to create a biodegradable cardstock composition. The biodegradable cardstock composition provides an alternative to conventional plastic cardstocks, which are manufactured using petroleum-based materials such polyvinyl chloride (PVC) or polystyrene (PS). The biodegradable cardstock described herein can be incorporated into a variety of end products such as key cards, driver licenses, security badges, calling cards, and other plastic cards, including those that have a magnetic strip containing stored data such as credit and debit cards.

Abstract: A bioderived plasticizer for biopolymers includes a compatibilizing unit and a polyester plasticizing unit. The plasticizer improves the flexibility of biopolymers while not adversely affecting the modulus of the biopolymer. The compatibilizing unit renders the plasticizer more miscible with the desired base biopolymer, and may increase crystallization and includes a lower alkyl (C3 to C7) organic acid including enantiomeric isomers of the base polymer. The polyester plasticizing unit is formed from monomers comprising a multifunctional alcohol and an aliphatic anhydride or its equivalent dicarboxylic acid and ester derivatives. The polyester plasticizing unit may optionally include one or more difunctional alcohols in combination with the multifunctional alcohol. The resulting bioderived plasticizer lowers glass transition temperature (Tg), can improve brittleness, may increases heat deflection temperature and improves melt viscosity.

Abstract: Biodegradable chewing gum bases containing one or more crosslinked polyesters, and methods of making and using thereof are described herein. In one embodiment, the base contains a first monomer derived from a saturated or unsaturated lipid, such as a saturated or unsaturated hydroxy fatty acid, optionally a second monomer derived from a saturated or unsaturated polyol, such as a saturated or unsaturated polycarboxylic acid or polyhydroxy compound, and optionally a third monomer, such as a saturated or unsaturated monocarboxylic acid, polycarboxylic and/or hydroxy acid having 5 carbons or less. The polyesters can be crosslinked in the presence of a free radical initiator via thermally-initiated or photo-initiated free radical polymerization. The chewing gum bases are rubbery at room temperature, have a low degree of tackiness and have low glass transition temperatures. One or more additive can be incorporated and/or active agents can also be incorporated into the chewing gum base.
