The paper studies the correlation between the structure and the thermal properties of some polyethers, using molecular simulation as a complementary method. The polymers were synthesized by phase transfer catalysis, starting from 3,3-bis(chloromethyl)oxetane and various bisphenols, as follows: 4,4'-dihydroxydiphenyl, bisphenol A, 4,4'-dihydroxy-diphenylmethane, 1,1 -bis-(4-hydroxyphenyl)ethane, 1,1 -bis-(4-hydroxyphenyl)cydo-hexane, 2,2-bis-(3'-methyl-4'-hydroxyphenyl)propane. 4,4'-dihydroxy-diphenylether, 4,4'-dihydroxydiphenyl-(1,2-ethane). The polyethers were characterized by thermogravi-metric methods and different scanning calorimetry. Molecular simulations were performed using a force-field program HYPERCHEM (version 4.5). This study permitted to select the most recommended structures for a subsequent cross-linking process. |
