    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.

    Abstract: Low VOC, unsaturated alkyd resins are obtained by reacting (A) to (E): (A) optionally from 0 to 30% w/w naturally occurring Rosin, comprising from 40 to 80 w/w parts per hundred of Rosin of an unsaturated mono carboxylic acid with at least one C15-25cyclohydrocarbo moiety capable of a Diels Alder or Ene reaction (preferred monoacids being abietic acid, palustric acid, levopimaric acid, sandaracopimaric acid, and/or anhydrides thereof); (B) from 25 to 80% w/w of a linear C12-60hydrocarbo carboxylic acid with at least one (preferably at least two conjugated) C═C bonds (=unsaturated fatty acid); (C) optionally from 1 to 30% w/w of an ethylenically unsaturated C5-6hydrocarbo dicarboxylic acid and/or anhydride thereof, being reactive as a dienophile and/or enophile with A and/or B (preferred for C are itaconic acid, citraconic acid and/or anhydrides thereof); (D) from 1 to 40% w/w of at least one polyol; (E) optionally at least one monomer other than A to D—the total of A to E being 100%. There is a further optional step (II) where more or new (C) may be blended with the alkyd resin; the amount of C in blend being from 1 to 30 parts w/w of 100 parts of monomers (A) to (E)—and where (C) is at least used as a monomer and/or as a diluent in the blend and where alkyd resin (i) has acid value of =1200 g/mol (iii) oil length =50%.
