Abstract

ABSTRACT The parent repeating sequence of elastin, poly(GVGVP), was synthesized using solution phase method and characterized by 13C- and 1H-NMR spectroscopy. In order to study the polymer–polymer interactions between poly(GVGVP) and hydroxyl propyl methyl cellulose (HPMC), the blends were prepared both in aqueous and solid phase and examined using various analytical techniques. The viscometric measurements have been carried out at 24 °C and the interaction parameters such as α, β, µ, and Δηm revealed the miscible nature of the poly(GVGVP)/HPMC blend systems. In addition, Fourier-transform infrared spectroscopy showed the formation of strong intermolecular hydrogen bond between poly(GVGVP) and HPMC networks. This result was further supported by glass transition temperature (Tg), scanning electron microscopic, and X-ray diffraction studies. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.
