The Viscoelastic Properties of Crosslinked Poly(Ethylene Tetrasulfide) Polymers. II.
Abstract
Stress relaxation studies were made on poly(ethylene tetrasulfide) crosslinked during the polymerization reaction by the use of trifunctional organic chloride. At very low crosslink densities a certain amount of stress-relaxation due to chain slippage occurred. Over the middle range of crosslinking density stress-relaxation was due to tetrasulfide bond interchange exclusively, and these samples followed maxwellian decay of stress. The specific rate constant for bond interchange (K) is given by K = 5.86 x 10 to the 12th power (exp - 25900/RT). The value of the activation energy obtained is discussed in the light of the various energy values reported for the scission of sulfur-sulfur bonds in sulfur chains and rings. (Author-PL).
