This work presents synthesis and characterization of copolymer obtained by grafting acrylic acid on hydrolyzed potato starch in the presence various initiators (azobisisobutyronitrile, potassium persulfate benzoyl peroxide). Starch hydrolysis was made to reduce average molar mass, i.e. macromolecule size. Grafting monomer performed produce a product that can be used textile treatment, for example, yarn sizing. Various were used, primarily, graft polymer obtain thinner or thicker packaging side chains have great influence behavior yarns impregnated with these copolymers. Potassium persulfate, as initiator, proved very successful starch, terms yield results, percentage efficiency. FTIR spectra grafted confirm their characteristic bands successful. Results show highest quantity is found sample peroxide. Molar masses hydrolyzate significant differences ranging from 1.83 × 103 7.13 106 g/mol.
