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(vinylchloride) plastisols. The products are also very good lubricants for many lubrication applications. Cette invention concerne divers produits d'esters de cétal alkyliques ou d'esters de cétal hydroxyalkyliques estérifiés qui sont utiles en tant que composants dans des compositions de polymères organiques. Les esters de cétal sont produits dans certaines transestérifications entre des esters de cétal alkyliques et/ou des esters de cétal hydroxyalkyliques et des polyols, des alcools aminés, des polyamines et/ou des acides polycarboxyliques. Les produits sont d'excellents plastifiants pour divers polymères organiques, notamment, les plastisols de polychlorure de vinyle. Les produits sont également de très bons lubrifiants pour de nombreuses applications de lubrification.
