This paper describes some synthetic methods for obtaining modified starches with n-alkyl chains derivatives from fatty acids and with polycaprolactone (PCL) and poly (ethylene oxide) (POE) chains. The degrees of substitution (DS) obtained in each case depend on the synthesis method and the length of the nature of the side chain. Most derivatives obtained were found to be stable at temperatures up to 250C and although most of these starches are not soluble in organic solvents, they swell in chloroform or THF. Finally, it was determined that in many cases the graft chains are able to crystallize in separate phases of the starch chain.Downloads
