Theory of the Kinetics of Conformational Transitions in Polymers

摘要

We develop a theory, valid for large friction, for the rate of conformational (rotational isomeric state) transitions in polymers. Such changes are classified according to the effect which the transformation in a finite portion of the molecule has on the attached polymeric chains. Major consideration is given to type 2* transitions, in which the attached chains are merely translated as the conformational alteration occurs. Study of a simplified model indicates that the rates of 2* transformations are not seriously inhibited by the attached polymer chains.
