Some Unsaturated Polyesters based on Maleic Anhydride Reaction Mechanism and Kinetic Study


Abstract:
This paper discusses the reaction mechanism and kinetic study of linear unsaturated polyesters, based on polycondensation reaction of maleic anhydride with different glycols (ethylene glycol, diethylene glycol and neopentyl glycol) utilized for the fabrication of polyurethanes. This polyester-diols with relatively high molecular weight (1000-1500) were characterized by IR, H-NMR, GPC, end groups analysis, as well as by the double bond content determination. Keywords: unsaturated polyester, reaction mechanism, kinetic study
