Interpenetrating polymer network of poly(bismuth acrylate) and ply(arsenicacrylate): Synthesis and characterization

IPN based on poly(bismuth acrylate) and poly(arsenic acrylate) have been sy nthesized by using BPO as initiator. Complex formation occurs through "poly mer solvent" method indicating contraction of polymer coils through weak va n der Waal's forces, by determining the value of mutual interaction constan t (K-AB) in different solvents such as DMSO, DMF, dioxane. The scanning ele ctron microscopy reveals a two phase morphology of both metal acrylates and the infrared spectrum indicates frequency of (>C=O) at 1640 cm(-1). The pr operties like percentage swelling, crosslink density, young's moduls are a direct function of linear polymer [polybismuth acrylate] and initiator [ben zoyl peroxide] where as inverse function of monomer [arsenic acrylate] and crosslinker [divinylbenzene]. The differential scanning calorimeter (DSC) c urve shows two glass transition temperatures of the IPN at 63 degreesC and 79 degreesC. The value of the activation energy, of IPN, calculated from th ermogravimetric analysis is 10.25 KJ/mol.
