Abstract: Weakly anionic semi‐interpenetrating polymer networks (semi‐IPNs), comprised of copolymer poly(N‐isopropylacrylamide‐co‐methacrylic acid) P(NIPA‐MA) and linear poly(acrylamide) (LPA) chains as macromolecular crowding agent, are designed to evaluate pH‐induced swelling and elasticity. Uniaxial compression testing after swelling in… read more here.

DOI: 10.3390/polym11050862
Abstract: Thermoplastic polyimide (TPI) was synthesized via a traditional one-step method using 2,3,3′,4′-biphenyltetracarboxylic dianhydride (3,4′-BPDA), 4,4′-oxydianiline (4,4′-ODA), and 2,2′-bis(trifluoromethyl)benzidine (TFMB) as the monomers. A series of semi-interpenetrating polymer networks (semi-IPNs) were produced by dissolving TPI in… read more here.
