RUBBER ELASTICITY OF PRESWOLLEN POLYMER NETWORKS: HIGHLY CROSSLINKED VINYLDIVINYL SYSTEMS.
Abstract
The rubber elasticity of highly crosslinked, presswollen network polymers was studied. Copolymers of tetraethylene glycol dimethacrylate with ethyl acrylate, n-butyl, acrylate, methyl methacrylate and styrene covering the whole range of composition are investigated. Dioctyl phthalate is used to preswell the polymers up to 50% by volume. Both shear moduli and front factors are found to increase with increasing crosslink concentration, but decrease with increasing diluent content. Crosslinking efficiencies are determined by a modified Lashaek-Fox method. They are relatively invariant with the degree of preswelling. Factors contributing toward these observations are discussed.
