Abstract
New siloxane-esters, useful as powder coating resins, are prepared by random condensation polymerization of a hindered glycol and a hydroxy functional silicone having about two ##STR1## groups per molecule wherein R is lower alkyl or phenyl groups and the remaining silicone valences form ring-structured siloxanes. Improved powder properties, including tack temperatures of 150.degree. F. to 220.degree. F., are believed to result in part from the hindered glycols especially those having carboxylic functionality.
