Spectroscopic Studies of Cyclization Dynamics and Equilibria,This chapter reviews cyclization of polymers and oligomers measured in real time by spectroscopic techniques. The requirement for such an experiment is that the macromolecules must have groups attached to the chain ends (e.g. D~~~~A) such that proximity of A and D, or reaction between A and D, gives rise to an observable event.

Introduction,lymers became fully established.. As described by Flory,. ring structures had been assigned to some polymers earlier in the century but they were later shown to be erroneous. It soon became accepted that synthetic polymers were based on long chain molecules that could be linear, branched or cross-li

Theory of Cyclic Macromolecules,reat beauty. Often the value of this research and its relation to applied polymer science has not been recognized. It is therefore not surprising that the theory of ring macromolecules is incomplete and fragmentary. Several gaps will become evident in this chapter, and only a few of them could be fi
