  • Patent number: 10323144
    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.

  • Patent number: 9139689
    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.

The polyester plasticizing unit may optionally include one or more difunctional alcohols in combination with the multifunctional alcohol. The resulting the bioderived plasticizer has a low glass transition temperature (Tg), preferably between ?20° C. to 30° C. The plasticizer is preferably amorphous.
