摘要: The elastic modulus of polyacrylamide-acrylic acid hydrogels is studied in a wide range swelling degrees. does not follow the concentration dependence predicted by rubber elasticity theory. At low degrees this can be attributed to constrained state (non-phantom behaviour) network chains. reason for increase at nigh seen finite extensibility and topological entanglements A theory including these effects proposed verified experiment.
