Abstract
The synthetic technology of acrylic acid--maleic anhydride copolymer sodium salt in aqueous system was detailed,the effect of monomer ratio,initiator amount and reaction temperature on conversion,molecular weight and performance of build detergent were studied.The optimum technical conditions were confirmed,the optimum amount in phosphrus free detergent powder was ascertained.The results showed that the copotymer′s properties had reached that of foreign product′s,and so,it would be a good substitute for triphosphate in detergent.
