Abstract The addition of N,N''-di-erucyl adipamide or N,N''-di-erucyl sebacamide to ionic copolymers comprising an Alpha -olefin of the general formula RCH CH2 where R IS A RADICAL selected from hydrogen and alkyl radicals having from one to eight carbon atoms and an Alpha , Beta -ethylenically unsaturated carboxylic acid having three to eight carbon atoms, the olefin content of said copolymer being at least 50 mole percent based on the copolymer, the acid monomer content of said copolymer being from 0.2 to 25 mole percent based on the copolymer, said copolymer having from 10 percent to 90 percent of the carboxylic acid groups neutralized with metal ions, one or more metal ions having ionized valences of 1 to 3 inclusive, the resulting film having improved slip/block properties without chalking.
