Abstract : The work described in this report consists of studies of combustion of Teflon monomer (C2F4), and studies of mechanical and electrical properties of polymers. In the Teflon flame studies, CF2 has been detected spectroscopically in both diffusion and premixed flames; CF was detected, with less certainty, in diffusion flames. In the polymer investigations, styrene-butadiene and ethylene-propylene rubbers of graded crosslink density have been studied mechanically in tension. A pulse method, devised for the very rapid measurement of dielectric constant and loss, is being evaluated.
