Abstract
Study presents compatibility behavior of polar group potato starch and non-polar LDPE using 50%, 0.5% maleated LDPE. The aim was to improve intermolecular interaction between two different types of moieties (LDPE and Potato Starch). Samples were prepared by mixing potato starch (upto 30% by weight) with LDPE and LDPE-grafted maleic anhydride in a single step twin screw extruder having vent zone. XRD and DSC results suggested that maleic-anhydride group of LDPE helped the interaction with starch and brought two chemical moieties closer to each other. FTIR results also strongly supported new bond formation between two chemical moieties.
