  • Patent number: 11932721
    Abstract: The present disclosure relates to methods for making polyols, esters, and surfactants. Generally, a carboxyl-containing molecule is reacted with an epoxide-containing molecule to obtain a hydroxylated ester. If multiple epoxide groups are present in the epoxide-containing molecule, the resulting molecule can also be considered a polyol. The hydroxyl groups can be further ethoxylated to obtain a surfactant/stabilizer.

  • Patent number: 11724981
    Abstract: A cationic surfactant and a method of making the cationic surfactant are described. The method comprises reacting a lipophilic bio-based material having at least one epoxy functional group and a hydrophilic organic compound having at least one cationic functional group and at least one hydroxyl functional group to form a reaction product containing a stable ether linkage connecting the lipophilic bio-based material to the organic compound. At least a portion of the cationic functional groups is neutralized or ion exchanged with an organic acid. Incorporation of the simple organic acid reduces the surfactant's aquatic toxicity and acts as a substrate to encourage co-digestion of the surfactant molecule, making the compound more biodegradable.

  • Patent number: 11560447
    Abstract: Processes for producing polymer microcapsules using vicinal functional oligomers are also described. The vicinal functional oligomers can be made by polymerizing an acrylate monomer, a styrene monomer, or both in the presence of a chain transfer agent. The vicinal functional oligomers can be reacted with epichlorohydrin to form vicinal epoxies. The vicinal epoxies can be reacted with polyamines to form epoxy polymer microspheres. The vicinal epoxies can be reacted with carbon dioxide in the presence of a catalyst to form vicinal cyclic carbonates. The vicinal cyclic carbonates can be reacted with polyamines to form isocyanate-free polymer microspheres. Polymer microspheres made by the processes are also described.

  • Patent number: 11426495
    Abstract: A chronically implanted medical device is disclosed that has an outermost layer formed from a conjugate of a polymer with lipoic acid, the conjugate having free 1,2-dithiolane groups. It is contemplated that this layer scavenges reactive oxygen species, i.e. acts as an antioxidant, and thus reduces inflammation and other adverse effects around the implant itself.
