Preparation and Properties of Modified Starch with Methoxy Polyethylene Glycol Methacrylate

Abstract:

The modified starch surfactant was synthesized by grafting copolymerization of methoxy polyethylene glycol methacrylate (MPGM) with starch. The effects of monomers composition and side chain length on surface activity of starch surfactants were investigated. The modified starch surfactant was synthesized when the molar ratio of AGU (starch) and MPEGMA was 1: 0.3 at 85 °C for 2h. The FTIR result shows that starch had successfully reacted with MPGM. Modified starch surfactants are poor foam surfactant with excellent surface activity. The modified starch surfactants are biodegradable and environmentally friendly and may be extensively used in various fields in future.
