A composition is disclosed which comprises a copolymer of ethylene and alkyl acrylate having improved melt-point temperature and/or improved adhesiveness to polymeric substrates. A process for making these compositions is also disclosed. In addition, an ionomer made from the copolymer and a method for making the ionomer are disclosed.

Ethylene-alkyl acrylate copolymers and derivatives having improved

Ionomer compositions which have improved optical properties are disclosed. These compositions comprise ionomers which can be represented as the polymerization product of alpha-olefins having from two to eight carbon atoms, esters of alpha, beta-ethylenically-unsaturated carboxylic acids, metal salts of acrylic and methacrylic acid, and optional alpha, beta-ethylenically-unsaturated comonomers which impart some desired polymer property or properties, such as acidity and/or solvent resistivity. Also disclosed are methods of making these ionomer compositions in a reactive extruder and treating the compositions with acid to impart acidity to the compositions or to only the surface of the compositions.
