Abstract: Disclosed is a process for esterifying and/or transesterifying a polymer having a polyethylenic backbone and pendant acid and/or ester moieties comprising contacting a melt of the polymer with a transesterifying compound so that the polymer undergoes esterification and/or transesterification but not alcoholysis. The esterified or transesterified polymer also has pendant ester moieties which differ in kind and/or number from the unreacted polymer. In one embodiment, the process also comprises adding an amount of a transition metal salt that is effective to promote oxygen scavenging. Also in a further embodiment, the process comprises irradiating the transesterified polymer with actinic radiation to reduce the induction period before oxygen scavenging commences.

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.

Abstract: Curing agents for epoxy resins composed of (a) the reaction product of a co-reactant comprising either an epichlorohydrin (co) polymer or a (co)polymer of a chlorovinyl acetate, chloroalkyl acrylate with an organic amino compound containing at least one active hydrogen and having a pK.sub.B value within the range of from about 7 to about 9, preferably imidazole and substituted imidazoles; (b) an N-fatty imidazole and (a); (c) an N-fatty imidazole and an elastomeric polymer are disclosed. The curing agents are essentially water insoluble and give rise to epoxy resins which may be cured at relatively low temperatures below about 100.degree. C. The epoxy resins are suitable for use as adhesives, coatings and in composite applications.
