Interpretive Summary:

Technical Abstract: Useful polymers can be made from vinyl esters of carboxylic acids. Depending on the length of the chain in the carboxylic acids, a variety of applications can be targeted. Specifically, if medium chain length carboxylic acids are used, an organogel is formed. These are used in a variety of high value applications including the removal of toxic solvents from aqueous environments and the time-controlled release of compounds. Current practice to make these compounds utilizes an expensive and low yielding transvinylation reaction. This makes production of useful vinyl esters and, as a result, the organogels themselves expensive. A more practical production process, reported here, utilizes commercially available polyvinyl acetate and accomplishes the transformation with simple hydrolysis and anhydride addition steps. The new polymers form organogels with a variety of organic solvents, with swell ratios up to 30. They also show time-controlled release of crystal violet over a 100 hour span. This new production process opens the possibility of producing organogels from biobased resources.
