Starch grafted polymers have attracted widespread attention due to their high viscosity,tempera-ture resistance,salt resistance,and biodegradability.However,the performance of the products is greatly affected by synthesis conditions,and the study of the principle and influencing factors of starch graft poly-merization reaction has guiding significance for the application of the products.The synthesis method and reaction mechanism of starch graft polymers were introduced,and the effects of monomer ratio of starch and vinyl monomer,reaction temperature,initiation method,pH value,starch gelatinization time,and reac-tion time on free radical polymerization were discussed.The performance of the product can be significant-ly improved by optimizing synthesis conditions.This article summarizes the research and application pro-gress of starch grafted polymers by domestic and foreign scholars in the fields of fluid loss additive,floccu-lants,adhesives,water-absorbing materials,adsorbents,corrosion inhibitors,etc.And new suggestions were put forward for the grafting synthesis method,and the future development trends of starch grafted polymers were discussed.
