Abstract
Various esterified alkyl ketal ester or hydroxyalkyl ketal ester products are useful as components of organic polymer compositions. The ketal esters are produced in certain transesterifications between alkyl ketal esters and/or hydroxyalkyl ketal esters and polyols, aminoalcohols, polyamines, and/or polycarboxylic acids. The products are excellent plasticizers for a variety of organic polymers, notable poly(vinyl chloride) plastisols. The products are also very good lubricants for many lubrication applications.
