Abstract
Abstract Aluminum acyloxide polymers are formed in a reaction involving approximately equimolar amounts of aluminum alkoxide, water and a branched chain, saturated aliphatic monocarboxylic acid having from about 10 to about 25 carbon atoms. These novel compounds from stable gels with non-polar liquids.
