    Abstract

    Relaxation of a dilute polymer solution after an abrupt cooling from good or Θ-solvent to poor solvent is considered. Four processes are involved in relaxation,namely, single unknotted chain crumpling, single-chain knotting, interchain aggregation, and interchain entanglement formation. Five different regimes are described depending on the relaxation times of these stages; they are presented on a T-c diagram of the solution. The interpretation of recent experiments of Chu at al. on the kinetic study of a coil-to-lobule transition is discussed.
