Abstract: A novel green polymer detergent builder was prepared by solution polymerization with 2-methylene-1,3-dioxepane(MDO) and acrylic acid (AA) as monomers. The effects of reaction time, MDO content, initiator content, and polymerization temperature on the properties of copolymer were investigated. The results show that synthetic copolymer P(AA-co-MDO) has excellent but controllable washing assisting properties and biodegradability. The chelating capacity, dispersing of P(AA-co-MDO) copolymer are 531.32 mg(CaCO3)·g-1, 133.03 mg(CaCO3)·g-1 respectively. The biodegradation rate is as high as 62.1% within 28 days.

Key words: biodegradable; polymer detergent builder; ring-opening copolymerization
