Abstract The invention relates to metal carboxylate derivatives of partially esterified .alpha.-olefin unsaturated polycarboxylic acid co- polymers, the .alpha.-olefin containing 6 to 40 carbon atoms and the copolymer being esterified with an alcohol. At least 80 percent by weight of the unesterified copolymer has a molecular weight in the range from 1000 to 100 000. Preferably, the .alpha.-olefin is maleic anhydride and the alcohol contains 4 to 18 carbon atoms. The present compounds are surprisingly satisfactory internal and external lubricants for synthetic resin such as PVC. Furthermore, the present compounds can be used as emulsifying and/or sus- pending agents, in particular when the alcohol is a polyethylene oxide glycol ether with 1 to 50 ethylene oxide units.
