Conformational Transitions of High-Molecular-Weight Poly(Methyl Methacrylate) in Dilute Solutions

This article deals with the investigation of high-molecular-weight poly-(methyl methacrylate) dilute solutions. The conformational transitions were followed as a function of temperature and solvent nature (ethyl acetate, butyl acetate, monochlorobenzene, o-dichlorobenzene) by using ultraviolet (UV)...

Zusammenfassung:	This article deals with the investigation of high-molecular-weight poly-(methyl methacrylate) dilute solutions. The conformational transitions were followed as a function of temperature and solvent nature (ethyl acetate, butyl acetate, monochlorobenzene, o-dichlorobenzene) by using ultraviolet (UV) spectrophotometry and viscometry. The systems involving ethyl acetate as a solvent presented some peculiarities in the temperature dependence of the UV spectra.
