Abstract: A continuous process for the aminolysis of polymers produced from ethylenically unsaturated structural units comprising contacting, in a reaction vessel, (a) a molten polymer containing structural units produced from alpha-olefins having from 2 to 8 carbon atoms, and esters of alpha , beta -ethylenically-unsaturated carboxylic acids in a reaction vessel; and (b) a liquid phase comprising an amine-containing compound, e.g., an alkylamine having an alkyl group containing 1-30 carbon atoms, ammonia, or derivatives thereof, in the presence of (c) a catalytically effective amount of a catalyst, which is preferably a metal-containing solution, for a period of time effective to produce a polymer containing acrylamide structural units, wherein the period of time is less than about 1 hour. This process is performed continuously in a reaction vessel, preferably in at least one reactive extruder, under conditions effective to provide an ethylene co-polymer containing acrylamide structural units.

Abstract: 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.
