Thermal degradation of allyl methacrylate—methyl methacrylate copolymers

Thermal Degradation and Flammability of Poly(methyl methacrylate) Containing TiO2 Nanoparticles and Modified Montmorillonite

“…A similar correlation was found earlier for PMMA filled with Sb 2 0 3 (16). The increase in the thermal stability of the polymer in the presence of such mineral fillers has been discussed in the literature on the basis of the restriction of mobility of the polymer chains resulting from their adsorption on the oxide surface via the methoxycarbonyl group, and of steric hindrance due to the presence of solid particles (17). In the present case of Ti0 2 , it can be assumed that the adsorption of polymer on the oxide particle surface is also responsible for the increase in thermal stability, probably by inhibiting a key step of the degradation mechanism.…”

Deposition and Characterisation of Plasma Polymerised Allyl Methacrylate Based Coatings

“…This increase of the amount of CH x bonds in the plasma coatings could be attributed to the polymerisation of the CC bonds that results in the formation of more CH x bonds, increasing the intensity of the CH x stretching bands. Another possible explanation is that during the plasma deposition some of the ester groups undergo an oxidative degradation leading to CO 2 as already proposed by McNeill and coworkers 26. A decrease of the monomer feed increasing the plasma power per monomer unit ratio, further decreases the CO:CH x ratio.…”

Renewable Polymers Prepared from Vanillin and Its Derivatives

“…The former stage corresponds to the decomposition initiated at the unsaturated chain ends of the polymers and the degradation of potential oligomers . The latter is attributed to the degradation initiated by random scission of polymers at high temperatures . Because of the higher unsaturation of MVA, its resulting polymers exhibit higher decomposition resistance in the lower temperature range.…”
