Polarographic determination of methyl methacrylate
Talanta, 1967The permanganate oxidation of methyl methacrylate in weakly acidic solution yields methyl pyruvate. Hydroxylamine hydrochloride is used for destroying the excess of permanganate. At the same time it is consumed for oximation of the pyruvate, and the resulting oxime is determined polarographically. The reaction scheme of permanganate oxidation of methyl

Thermodynamic properties of polymethyl methacrylate and methyl methacrylate
Journal of Polymer Science Part A: General Papers, 1963AbstractFrom published data the entropy, enthalpy, and Gibbs free energy of polymethyl methacrylate (PMMA) have been calculated over the temperature range 0–260°K. These functions have also been calculated for methyl methacrylate over the range 0–210°K. The entropy of polymerization at 210°K. was found to be 9.63 cal./mole°K.

Graphene was covalently functionalized with phenol groups by a 1,3-dipolar cycloaddition reaction without degrading its electronic properties. Here, these phenols on the functionalized graphene have been further derivatized with 2-bromoisobutyryl bromide
