Development Studies of Biodegradable Pressure Sensitive Adhesives from Groundnut Oil and Butylmethacrylate

The use of annually renewable resources and the biodegradability or recyclability of the product is becoming important criteria. Preparation of groundnut oil based polymeric materials has been investigated. The biodegradable acrylated epoxy resin was prepared by the insitu epoxidation of groundnut oil using controlled reaction conditions. The effect of proceeding conditions on hydroxylation of epoxy resin was evaluated. Acrylated epoxy resin was analysed by IR spectral analysis. Biodegradable pressure sensitive adhesive was prepared using comonomer butylmethacrylate. The effect of comonomer concentration on the peel strength and shear strength of the pressure sensitive adhesive was evaluated. Bacterial adhesion of the adhesive was studied using bacterial strains and the bacterial attack degradation of pressure sensitive adhesive was evaluated. Due to the bacterial adhesion it also serves as a bacteriostat on a plastic surface to prevent the growth of bacteria. The pressure sensitive adhesive can be used in many biomedical applications.
