Biocompatible polymer blends : Effects of physical processing on the molecular interaction of poly(vinyl alcohol) and poly(vinyl pyrrolidone)
Jones, S. A.; Martin, G P; Royall, P.G.; Brown, Marc (2005-12-05)Blending is a very effective method for manufacturing new polymeric materials; however, the process used to combine two polymers can influence the physicochemical properties of the final product. As such, the aim of this ... -
The development of DMA for the detection of amorphous content in pharmaceutical powdered materials
Royall, P.G.; Huang, C-Y.; Tang, S W J; Duncan, J.; Van-de-Velde, G.; Brown, Marc (2005)The aim of this short study was to develop a novel method of sample presentation that will allow currently available DMA apparatus designed for the testing of self-supporting materials to detect amorphous content in ... -
The development of powder pocket dynamic mechanical analysis for the detection of amorphous content in salbutamol sulphate: a feasibility study
Tang, S. J.; Duncan, J.; Van-de-Velde, G.; Brown, Marc; Royall, P.G. (2005-09)Dry powder inhalers are a commonly prescribed dosage form for the treatment of asthma. In essence they consist of an active compound in particulate form (1–5 m diameter) adhered loosely on the surface of a larger inert ... -
