Structure-Mechanical Property Relationships in Ethylene Methacrylic Acid Copolymers and Their SaltsPolymer Engineering & Science (1968)
A dynamic mechanical study has been made of an ethylenemethacrylic acid copolymer containing 4.1 mole per cent of methacrylic acid units and its sodium, lithium and calcium salts. On the basis of the results and related physical chemical studies it is proposed that the structures of the ionized copolymers consist of three distinct phases-a crystalline polyethylene phase, an amorphous polyethylene phase, and an ionic phase consisting of ionic domains. It is further proposed that the unionized acid copolymer consists of two phases-a crystalline polyethylene phase and an amorphous phase consisting of polyethylene crosslinked with hydrogen bonded, carboxylic acid dimers.
