Utilization of glycerol phase by synthesis of alkyd-methyl methacrylic copolymers

Abstract

Glycerol phase obtained from waste cooking oil-based biodiesel production, was utilized. By suitable treatment, crude glycerol (glycerol content 80,8%) and free fatty acids (98,8% content and iodine value 124,3 gI2/100 g) were obtained from it. Aiming to obtain coatings with good characteristics, modification with MMA was carried out. Composition and structure of copolymers were confirmed by 1H NMR. Assessment of the main characteristics of the prepared films from the copolymers, showed that they have improved hardness, drying ability and resistance to alkaline substances.
