To evaluate the scaling parameters of weakly cationic crosslinked network structures, poly(dialkylaminoethyl methacrylate)-based hydrogels were synthesized via free-radical crosslinking in aqueous solution varying systematically concentration of pregel solution Based on the gel-preparation concentration, variation in structural properties, effective crosslinking d., average mol. weight of polymer chains, and thermodn. parameters from combined swelling and elasticity results were discussed using the scaling theory to predict various exponent identities. The concentration dependence of compressive elastic modulus as-prepared state was described by a power-law relation G0â?ν20)m with the exponent of m = 3.55 indicating the importance of the trapped entanglements. Two structural characteristics, the network chain length N and the average mol. weight of polymer chains have inverse dependence on the gel-preparation concentration in the matrix, while the compressive moduli and effective crosslinking d. show completely direct dependence. Exptl. determined N values of PDMAEMA hydrogels first decrease with increasing ν20 up to 0.2972 and the dependence of N on the gel-preparation concentration gives the relation NâX-1(ν20)n with a scaling parameter n = -1.80, which coincides with the prediction of scaling theory. Acceptable agreement was found between the estimate of crosslink d. fluctuations deduced from mech. measurements and the results derived from independent swelling observations. © 2019 Wiley Periodicals, Inc.
