Metal carboxylate derivative for use in synthetic materials, emulsions and suspensions

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