The Strength of Thermoplastic Materials. Part 2. A Theory for Material Strength and Its Application to Liquid Stress Cracking.

摘要

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.
