Amphiphilic Graft Copolymers in Selective Solvents: Molecular Dynamics Simulations and Scaling Theory

Original language description

Intramolecular structures in amphiphilic graft copolymers with hydrophilic side chains and hydrophobic backbone have been studied by molecular dynamics simulations. We have found that balance of repulsive and attractive intramolecular interactions may result in the pearl-necklace-type conformations. The globular ?pearls? are formed by collapsed segments of the main chain comprising multiple spacers; these pearls are stabilized against aggregation by repulsive interactions of the hydrophilic grafts. Thesize of the pearls is controlled by the intramolecular hydrophilic-hydrophobic balance, whereas the total number of pearls in the graft copolymer depends on the length of the main chain. The results of simulations, in particular behavior of polymers of finite chain length, are rationalized on the basis of revised and extended scaling theory.
