     JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract This review presents poly(dimethylphosphazene) (PDMP), as the simplest representative of poly[(organo)phosphazenes], which was used as the additive into commercial polymer mixtures. This mixture was electrostatically spun. The formation and behaviours, such as wettability, of PDMP modified layers, were investigated. Phosphazene; Poly(dimethylphosphazene); Electrospinning; Nanofibers Introduction and Theory The effort to make new materials from already well-known compounds is the goal of many current scientists. The synthetic possibilities in polyphosphazenes chemistry has enabled the development of a wide range of matrixes with a variety of physical, chemical, and biological properties. Poly[(organo)phosphazenes] introduce a unique class of extremely versatile compounds with huge potential for various applications. Due to their high ability to be functionalized by a wide range of side groups, [1]...

   JUNIPER PUBLISHERS-   ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract The dynamic rheological behavior of a polymethylvinylsiloxane (PMVS)/ low density polyethylene (LDPE) blending melts at 150,180 and 210 ℃ is investigated by small amplitude oscillatory shear on a rotational rheometer. LDPE has higher viscosity than PMVS at three temperatures, which affects the morphology and rheological response of the blends. The LDPE-rich blends have smaller dispersed droplets and longer relaxation time than the PMVS-rich blends. Higher temperature means less viscosity as well as dynamic modulus difference between the LDPE-rich blend and the PMVS-rich blend. Increasing temperature fastens relaxation of polymer samples thus relaxation time at higher temperature is shorter than that at low temperature. Phase separation can be shown at some weight ratio of PMVS/LDPE through the failure of time-temperature superposition principle and double peaks of relaxation time including the form rela...
