Abstract:

The manner in which polymers, with phenylene groups in the main chain, break on contact with certain liquids, has led to the development of a tentative theory regarding the initiation mechanism of breaking of polymers when failing under stress alone and has resulted in a molecular theory of polymer strength which appears to predict the strength of the material from surface free energy and a consideration of molecular geometry. One result of the theory is the possible prediction of the maximum strength of a polymer from the chemical configuration of the monomer.
