The utilization of the swelling capacity of a system in selected solvents and in water to the determination of its structure has been discussed on the ex ample of an IPN-system composed of poly(methacrylic acid)-co-(divinylbenzene)/polystyrene-co-(divinylbenzene). An increase in the concentration of elastically active chains of the system network as compared with the irconcentration in the matrix-forming copolymer as well as the deviations from additivity of the values of Network parameters indicato for the fact that in the IPN-system studied there are regions of interpenetration between two immiscible copolymers.
