“…GP minimized without applying ultrasonic and ultrasound has played a catalytic role on the PP grafting rate. The reason is that the unique ultrasonic cavitation can promote homogeneous interfacial turbulence and heterogeneous interfacial update [7] . Interface agent may carry the monomers and initiator spread into the interior PP quickly and accelerate the swelling process of PP.…”

Polypropylene (PP) was grafted with styrene (ST), maleic anhydride (MAH) and butyl acrylate (BA) by free radical thermal initiation leading to (PP-g-PSMB) in water suspension system. The effects of ultrasonic frequency and time were investigated on PP grafting ratio in swelling stage. The structure of grafted product was analyzed by FTIR and melt flow rate (MFR), die swell ratio (Dr) and water contact angles of the grafted product were tested. The results show that the grafting ratio of PP can be improved in a short time by using ultrasonic significantly. The grafting ratio of PP increased with the increase of ultrasonic frequency. Ternary-monomer was grafted onto the PP chain branching in the form of long chain uniformly. The surface polarity of the grafted product was improved significantly.
