WebFeb 22, 2006 · A novel semi-interpenetrating polymer network (semi-IPN) gel consisting of an AAm gel and linear PAAc chains was designed and developed. The semi-IPN gel was simply prepared by infiltrating PAAc chains into AAm gel networks from an outer PAAc solution through immersion of AAm gels in the PAAc solution. The semi-IPN gel swelled … WebThe idea behind semi-interpenetrating networks (semi-IPNs) is to combine the processability of thermoplastic polymers with the high temperature performance of cross-linked thermosetting materials. Such mixtures should possess the desirable features of both types of materials.
