Preparação e caracterização de blendas formadas por goma xantana e poli (alcóol vinílico) para aplicação na área de liberação controlada de fármacos.

Polymer blends are a quick and economical way to obtain materials with modular properties and achieve different properties desired in the design of controlled release of drugs in order to meet the therapeutic needs systems. The objective of this work was the preparation and characterization of polymeric films xanthan ( GX ) and poly ( vinyl alcohol ) ( PVA ) chemically crosslinked with citric acid (CA ) for further application in controlled release of drugs . Infrared analysis showed possible interactions between the polymers in the blend and the incorporation of crosslinker into the polymer matrix. Tests of solubility and swelling of the blends GX / PVA / AC showed synergism of the properties of GX / AC and PVA / AC in the blend films. The films showed good thermal stability both in argon atmosphere as in synthetic air, and the PVA film / best AC stability in the two atmospheres
