The results demonstrated that, under the same strengths, the kinetic aspects of intrachain and interchain interactions raise much higher diffusion energies than their thermodynamic aspects. We discussed the example case of polyethylene. Our work paves the way towards the prediction of the structure-...
Herein, the term alkyleneglycol moiety covers oligo- and polyalkyleneglycol moieties as well as monoalkyleneglycol moieties. Polyalkyleneglycols comprises polyethyleneglycol based, polypropylene-glycol based and polybutyleneglycol based chains, i.e., chains that are based on the repeating unit —CH2CH2O...
