Abstract:
Mixtures of neutral and charged polymers are studied by Monte Carlo simulation techniques. The charges on the chains are assumed to interact with a Debye-Hückel potential. The monomer density and the screening are kept constant, while the proportion between charged and neutral polymer is changed. The single-chain structure factor of each species is analyzed, and drastic changes arc observed with the variation of the fraction of charged chains. Changes entail modifications of the radius of gyration, which suggest the existence of attractive interactions. Results agree with experimental evidence of incompatibility in mixtures at low polyclectrolyte concentrations.
