Abstract
Novel ionomers of normally solid, thermo-plastic, orientable, copolymers of ethylene and at least one alpha,beta-ethylenically-unsaturated carboxylic acid having a relatively high content of the carboxylic acid are prepared under conditions whereby the copolymers are essentially solubilized in a strong base and contacted with at least one compound which contains ionomer-forming cations. One of the preferred polymers is an ethylene/acrylic acid copolymer. The so-formed ionomers are useful as materials for constructing various items and articles.
