The thermal degradation of poly(iso-butyl methacrylate) and poly(sec-butyl methacrylate)

The thermal degradation of poly(iso-butyl methacrylate) and poly(sec-butyl methacrylate)

The non-oxidative thermal degradation of poly(iso-butyl methacrylate) and poly(sec-butyl methacrylate) was investigated by studying changes in the polymer residue. Due to the different number of b-hydrogens in their ester substituents, these two polymeric isomers behave differently when subjected to...
