Coupling Between Fluid Ingress and Mechanical Strain or Stress

It was also recorded that certain chemicals caused scissions within polymeric chains and of side groups. Relevant data are given in Table 4.1, demonstrating a strong dependence on temperature and activity that brings about weight losses in exposed samples.

10 Coupling Between Fluid Ingress and Mechanical Strain or Stress 

Since the configurations of the polymeric chains are affected by mechanics-based factors, as well as by the magnitude of the free volume, they necessarily interact with the diffusion process. Unlike the aforementioned case of creep, the imposition of a constant strain would presumably maintain all fully relaxed polymeric chains at nearly fixed configurations during fluid ingress and thus yield data that may be largely uncoupled. Accordingly to this supposition such data - collected
