The Viscoelastic Properties of Crosslinked Poly(Ethylene Tetrasulfide) Polymers.
Abstract
A range of crosslink densities have been introduced into poly(ethyl tetrasulfide) by use of the trifunctional agent, 1,2,3-tricholoropropane. The formation of a crosslinked structure has been established by torsional modulus measurements over a range of temperatures from the glass transition region to a region of rapid stress decay due to interchange reactions between polysulfide linkages. Estimates have been made of the deviation from ideal rubber elasticity by calculating the front factors. The density of crosslinked poly(ethyl acrylate) was found to increase with the amount of crosslinking up to 35% crosslinking agent, and then to fall steeply at higher crosslink densities. Samples containing less than 5% crosslinking agent showed evidence of crystallization. (Author-PL).
