This disclosure relates to a process for forming plastics from a melt of a mixture of plastics, stabilizers, antioxidants and lubricants, wherein the lubricants comprise a derivative of a copolymer of unsaturated polycarbonic acids or the anhydrides thereof and .alpha.-olefins having an average of at least 28 carbon atoms.

Shaping of plastic materials containing polymeric lubricant

This invention relates to moldable thermoplastic compositions comprising a thermoplastic polymer admixed with a minor shaping processing improving amount of an esterified olefin-maleic anhydride copolymers formed from olefins having 2 to about 24 carbon atoms, where the esterifying alcohol is a monovalent alcohol having 2 to about 20 carbon atoms and where the ratio of maleic anhydride to esterifying alcohol is about 1:0.5 to about 1:2.
