The Monte Carlo method was used to simulate chains with charged monomers interacting by screened Coulomb potential. The neutral polyampholyte chains collapse due to the attractive electrostatic interactions. The nonneutral chains are in extended conformations due to the repulsive polyelectrolyte effects that dominate the attractive polyampholyte interactions. The results are in good agreement with experiment.337-344engPOLYAMPHOLYTE COPOLYMERSMONTE CARLO SIMULATIONMACROMOLECULESPOLYAMPHOLYTE EFFECTArtigo10.1080/08927029308022518WOS:A1993MV04100002Acesso restrito
