Flexible aliphatic poly(isocyanurate-oxazolidone) resins based on poly(ethylene glycol) diglycidyl ether and 4,4?-methylene dicyclohexyl diisocyanate
New flexible aliphatic oxazolidone-isocyanurate networks (AISOX) are obtained by reacting a low molecular weight diisocyanate (4,4?-methylene dicyclohexyl diisocyanate, H12MDI) and a macro-diepoxyde (poly(ethylene glycol) diglycidyl ether, Mn = 526, PEGDGE) in different molar ratio. The curing reaction, carried out from 25 C to 200 C, is studied by using DSC and FTIR. The effect of the molar ratio of the two monomers on thermal and mechanical properties of AISOX resins is investigated by DSC, thermogravimetric analysis, stress-strain measurements and optical microscopy. Independently from the feed composition, it is observed that the reaction steps are: (i) partial hydrolysis of isocyanate caused by water traces, (ii) incomplete trimerization of isocyanate to give isocyanurate, and (iii) formation of oxazolidone and complete conversion of isocyanate. At the highest concentration of the soft macrodiepoxyde (PEGDGE), the AISOX resin is in the rubbery state at room temperature and shows an elastomeric behavior.
