  The present invention is directed to formulations including a polymer and a plasticizer composition. The plasticizer composition is a blend of an alkyl ketal ester plasticizer and a second plasticizer selected from a cycloaliphatic compound, an ortho phthalate compound, a terephthalate compound, a benzoate ester compound, and a bio-based compound. The plasticizer composition is at least 10% by weight of the total of the polymer and the plasticizer composition.

  Disclosed herein is a polyketal adduct obtained by forming an ester between a hydrocarbon polyol and a ketocarboxylic acid to produce an intermediate polyketocarboxylic ester. The intermediate polyketocarboxylic ester can be purified via crystallization to achieve purities of greater than 99.0% and then ketalized to produce the polyketal adduct, which can be used in polymer compositions. The polyketal adduct I is obtained at high purity and at high yield.

  A polymer composition containing cellulose acetate in combination with one or more plasticizers and one or more acid scavengers. The composition can also optionally include one or more bio-based polymers. The polymer composition is formulated so as to have properties similar to petroleum-based polymers for producing, for example, single-use biodegradable articles.
