Thermal degradation of net polymethacrylates based on oligomers with conjugated acetylene groups

The thermal degradation of net polymethacrylates based on oligomers with conjugated acetylene groups has been investigated by thermogravimetry and pyrolysis gas chromatography over a wide temperature range. It has been found that the nature of the thermal degradation depends basically on the presence of conjugated ene-yne bonds ▪ in the net polymer matrix.
