  • Patent number: 11999874
    Abstract: Provided are a thermoplastic polymer and a method of forming a thermoplastic polymer. The thermoplastic polymer includes a thermoplastic polymer including one or more fatty acids derived from a plant-based oil. In some embodiments, the thermoplastic polymer includes a structure according to the formula (C18HxO2)y, wherein each x is individually selected from the group consisting of 32 and 33, and wherein y is between 1 and 300. The method of forming a thermoplastic polymer including epoxidizing a plant-based oil to form an epoxidized plant-based oil; saponifying the epoxidized plant-based oil to separate the fatty acids from the glycerol; and then polymerizing the separated fatty acids to form the thermoplastic polymer.
