Mechanism and kinetic peculiarities of early stases of the low-temperature degradation of epoxy amine polymer

摘要

Low-temperature destructioin of epoxypolymer on the base of olygomer ED-20 and polyethylenepolamine was studied by the method IR-spectroscopy. It was shown, that change in the IR-spectrums on the first stages are determined mainly by thermal transformations of the bounds of oxypropylene group of the polymer chain. The disintegration energy these bounds differ unessentially. Possible schemes of the transformation in the polymer matrix which are accompanied by accumulation in the system of the unsatured and carbonyl-compounds are examined.
