Enhanced Controlled Transdermal Delivery of Mexazolam Using Ethylene-vinyl Acetate

   Repeated oral administration of mexazolam, an anti-anxiety agent, may cause adverse effects such as gastric disturbance, drowsiness, and ataxia due to transiently high blood levels. Transdermal administration would avoid the systemic side effects and gastric disorders after oral administration. We have developed a matrix using ethylene-vinyl acetate (EVA), a heat-processible and flexible mat...

Non-isothermal crystallization and melting of ethylene-vinyl acetate copolymers with different vinyl acetate contents

Non-isothermal crystallization and subsequent melting of three grades of ethylene-vinyl acetate copolymer were investigated by differential scanning calorimetry (DSC) technique. The DSC crystallization curves show that vinyl acetate (VAc) content has the same effect on the onset, peak and final crystallization temperatures, and these copolymers have almost the same spacing of thermal windows un...

Miniemulsion Copolymerization of Ethylene and Vinyl Acetate

The copolymerizations of a gaseous monomer (ethylene) and a liquid monomer (vinyl acetate) via emulsion and miniemulsion polymerizations are reported. Reactions in which the vinyl acetate was introduced in both batch and semibatch modes are carried out. (Ethylene introduction is always in a semibatch model since the polymerization is carried out under a constant pressure of ethylene in the reac...

Normal Coordinate Analysis of Poly Vinyl Acetate

Fourier transform infrared and Raman spectra of poly vinyl acetate and its deuterated derivative were recorded and observed frequencies were assigned to various mode of vibration in terms of fundamentals and combinations by assuming Cs point group symmetry. A normal coordinate analysis was also carried out using simple valence force field. A complete vibrational analysis is presented here for t...
