Summary

A series of monodisperse oligo(methyl methacrylates) of well-defined structure has been prepared and used to assess the thermal stability of groups formed in the termination of radical polymerization of methyl methacrylate. The role of head-to-head linkages and unsaturated ends as defect structures in poly(methyl methacrylate) (PMMA) is confirmed and the relative stability of these groups is established. The half-lives for oligo(methyl methacrylate) “decamers” containing head-to-head and unsaturated linkages at 240°C in nitrogen are 72±3 min. and 19±2 min., respectively. Some limitations on Thermogravimetry when used for the quantitative analysis of PMMA are addressed.
