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.
