  • Ketal compounds from polyols and oxocarboxylates
    Patent number: 8604077
    Abstract: Novel ketal compounds can be made from an oxocarboxylate and a triol. Novel polymeric structures are, in turn, synthesized from the ketal compounds. Such ketal compounds and associated polymers are useful in a broad range of applications as a substitute for materials derived from petroleum or other such nonrenewable resources.

  • Polyketal Compounds, Synthesis, and Applications
    Publication number: 20110021658
    Abstract: The invention relates to polyketal compounds. The compounds are synthesized by the selective ketalization of oxocarboxylic acids, e.g. keto acids and semialdehydes, and esters thereof with tetrols and higher polyols that products two or more cyclic ketal ester moieties per molecule, wherein the cyclic ketal moieties are situated in a bis-, tris-, or polyketal conformation. The invention further relates to applications of these compounds and subsequent reactions thereof.
