Dielectric And Mechanical Relaxations In Ethylene-Acrylic Acid And Ethylene-Methacrylic Acid Copolymers, William Macknight, F. A. Emerson Dec 1971

Dielectric And Mechanical Relaxations In Ethylene-Acrylic Acid And Ethylene-Methacrylic Acid Copolymers, William Macknight, F. A. Emerson

William MacKnight

The dielectric relaxation behavior of ethylene-carboxylic acid copolymers has been studied over the frequency ° range of °SO Hz to 10 f Hz and over the temperature range of -160 C to+ 100 C. The copolymers studied consisted of four acrylic acid and two methacry­lic acid copolymers of varying acid content. In the temperature and frequency region investigated, two dielectric dispersions occur and these are labelled B' and yin order of decreasing temperature. The B' dispersion may be quantitatively accounted for on the basis of the orientation of free carboxylic acid groups. The concentra­tion of these groups is assessed from …


Infrared Dichroism Studies Of The Relaxation Of Ethylene-Methacrylic Acid Copolymers And Their Salts, William Macknight, Y. Uemura, R. S. Stein Dec 1970

Infrared Dichroism Studies Of The Relaxation Of Ethylene-Methacrylic Acid Copolymers And Their Salts, William Macknight, Y. Uemura, R. S. Stein

The change in infrared dichroism with elongation has been observed at a series of temperatures for several infrared bands of ethylene-methacrylic acid copolymers and their salts. The orientation functions of hydrocarbon and meth­acrylic acid parts of the molecule were calculated as a function of the temperature of stretching. It is found that the orienta­tion function-strain coefficient for the un-ionized acid decreases uniformly with temperature, but that for the ionized salt passes through a maximum at about 40° where the strain-optical coefficient has been observed to pass through a maximum. Maxima are observed for the dichroism-strain coefficients for both the hydrocarbon …
