Thermal degradation of poly(n-butyl methacrylate), poly(n-butyl acrylate) and poly(t-butyl acrylate)

Journal of Analytical and Applied Pyrolysis, 2013
Abstract Direct pyrolysis mass spectrometry findings revealed that thermal decompositions of poly(n-butyl methacrylate), PnBMA, poly(n-butyl acrylate), PnBA, and poly(t-butyl acrylate), PtBA, follow different decomposition pathways. Among these polymers thermal degradation via depolymerization is only major decomposition routes for PnBMA.

Gas sorption and transport in poly(tertiary-butyl methacrylate)

Polymer, 1997
Abstract Gas sorption and transport properties of poly(tertiary-butyl methacrylate) (PtBMA) have been measured at 35°C and are compared with prior results for poly(methyl acrylate) (PMA), poly(methyl methacrylate) (PMMA), and poly(ethyl methacrylate) (PEMA).

Chitosan and Poly(Methyl Methacrylate-Co-Butyl Methacrylate) Bioblends: A Compatibility Study

Polymer-Plastics Technology and Engineering, 2014
Chitosan/poly(methyl methacrylate-co-butyl methacrylate) (PMMA-co-BMA) blends were prepared via a solution blending method in the presence of formic acid. The compatibility of the bioblends was studied by different methods, such as Fourier transform infrared and Raman spectroscopy, micro-Raman imaging, thermogravimetric analyses, differential scanning ...

Molecular Mobility in Poly(butyl methacrylate) and Poly(methyl methacrylate)

Molecular Simulation, 2004
Molecular mobility is studied in poly(butyl methacrylate) and poly(methyl methacrylate) (PMMA) with molecular dynamics simulations in order to understand the effect of the α–β crossover on the β relaxation activation energy and co-operativity. In the high frequency range investigated, the estimated β process activation energy is decreased as compared ...

Compatibility of peo/poly(iso-butyl methacrylate) and peo/poly(tert-butyl methacrylate) blends by DTA

Materials Letters, 1995
Abstract Melting temperatures and crystallization rates of poly(ethylene oxide)/poly(iso-butyl methacrylate) and poly(ethylene oxide)/poly(tert-butyl methacrylate) blends of different compositions were studied by differential thermal analysis (DTA). The equilibrium melting temperatures were found to decrease, for a given T C or ΔT m , as the

Conformational transitions in poly(butyl methacrylate)

Polymer Bulletin, 1987
Temperature dependence of viscosity data was investigated on poly(butyl methacrylate) fractions in dilute solution. A discontinuity in intrinsic viscosity was observed in the 25°C–35°C temperature range. Sharp changes of unperturbed dimensions were visualized from this behaviour. The phenomenon can be accounted for by assuming conformational changes of
