Notes:
The rubber elasticity of highly crosslinked, preswollen network polymers is 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 to decrease with increasing diluent content. Crosslinking efficiencies are determined by a modified Loshaek-Fox method. They are relatively invariant with the degree of preswelling. Factors contributing toward these observations are discussed.
