ABSTRACT:
A process for polymerizing unsaturated dicarboxylic acids comprises heating the acids in the presence of a catalytic proportion of an unactivated clay and water. The product dimer is distilled to separate unreacted monomer acids. The product dimers of 36, 40 and 44 content are useful as corrosion inhibitors, epoxy resin curing agents, lubricants and intermediates for synthetic polymeric resins and polymeric resin plasticizers.
