Polymer Configurational and Compositional Variables as a Function of Molecular Weight

Molecular weight and molecular weight distribution have been shown to markedly affect the mechanical properties of polymers, and this subject has recently been reviewed [l]. In this review by Martin et al. it was pointed out that indirect effects, i.e., such other changes as branching and orientation, can markedly affect the mechanical properties, also. This review is concerned with variation in the configurational and compositional variables of polymers as a function of molecular weight.
