Methacrylate-co-N-methyl Glutarimide Random Copolymers

Another series of methyl methacrylate copolymers is constituted by the methyl methacrylate-co-M-methyl glutarimide random copolymers. The chemical structure of the N-mclhyl glutarimide repeat unit is  

These copolymers will be coded MGIMx, where x indicates the mol% of glutarimide units in the copolymer. 

The copolymers are obtained by the reaction, in solution, of methylamine with PMMA, leading to methyl glutarimide (MCI) cycles randomly distributed along the original PMMA chain backbone. As the content of MCI units varies from 4 to 76%, it is worth considering the percentages of the different triads that can be encountered (the calculations are performed as- 

Calculations performed on the basis of a random distribution of the MGIM and MM A units 

Compared to the CMIMx chemical structure, the main differences are
