非剛体粒子分散系のレオロジー的性質

抄録

The steady-flow, linear and nonlinear viscoelastic properties of disperse systems of swollen styrene-divinylbenzene copolymer particles were measured for a wide variety of the degree of cross-linking by means of a Weissenberg Rheogoniometer. The rheological properties of disperse systems in which each particle does not reach the state of equilibrium swelling, depend strongly on the boundary layers between neighboring particles. The lower the degree of cross-linking of particles, the higher the storage and loss moduli of the disperse system. The nonlinear viscoelasticity of these disperse systems are compared with those of suspensions of rigid particles.
