Title

Supercritical Fluid Process for Synthesis of Maleated Poly(Vinylidene Fluoride)

Abstract

Poly(vinylidene fluoride) was grafted with maleic anhydride monomer via a free‐radical mechanism in supercritical carbon dioxide medium. The free‐radical initiator chosen for this study was benzoyl peroxide. The structure of the resultant copolymer pendant groups was determined by 1H NMR spectroscopy to consist of individual succinyl anhydride functional groups. The degree of functionalization (graft level) was obtained by FTIR spectroscopy through the correlation of absorbance bands using standard samples. The FTIR analysis indicated increased graft level with monomer loading, reaction temperature, and treatment time; however, initiator loading and reaction temperature showed more‐complex behavior. Graft levels increased at moderate benzoyl peroxide initiator loadings (5.0 wt%) and decreased at the highest initiator loadings (10.0 wt%).
