Chitosan and Poly(Methyl Methacrylate-Co-Butyl Methacrylate) Bioblends: A Compatibility Study
Polymer-Plastics Technology and Engineering, 2014Chitosan/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, 2004Molecular 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 ...

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, 1987Temperature 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

Radiolysis of the isomeric poly(butyl methacrylates)
Journal of Polymer Science Part A: General Papers, 1963AbstractA study has been made of the effect of gamma irradiation on the production of free radicals in poly(butyl methacrylates). A mechanism of radiation attack on the polymers is proposed. Free‐radical measurements and the determination of the products of irradiation have been used in establishing this mechanism.

Poly(methyl methacrylate) and Poly(butyl methacrylate) Swelling in Supercritical Carbon Dioxide
Macromolecules, 2001Swelling of poly(methyl methacrylate) and poly(butyl methacrylate) samples in supercritical carbon dioxide and propagation of diffusion fronts in the samples were studied in situ at various temperatures and pressures using direct optical observation. The difference in the appearance of diffusion fronts in these polymers with different glass transition ...

Industrial & Engineering Chemistry Research, 2008
The photocatalytic degradation of the homopolymers, poly(methyl methacrylate) (PMMA), poly(butyl methacrylate (PBMA), and their copolymers (PMMABMA) was studied in o-dichlorobenzene in the presence of commercial $TiO_2$ (Degussa P-25) and $TiO_2$ synthesized by combustion synthesis $(CSN-TiO_2)$.

Morphology of Poly(2-ethylhexyl methacrylate):Poly(butyl methacrylate) Latex Blend Films
Macromolecules, 2001This paper describes the morphology of the latex films formed from a mixture of two different latex particles: poly(butyl methacrylate) (PBMA, 120 nm) and poly(2-ethylhexyl methacrylate) (PEHMA, 100 nm). Twenty percent of the PBMA phase is labeled with 1 mol % anthracene.
