Study on Hydrophilicity of Hydroxymethyl Acrylamide Grafted Polypropylene

FENG Jie,FENG Shaohua,XIANG Yixin,FENG Chang(Departement of Polymer Science and Engineering,Qingdao University of Science & Technology,Qingdao 266042,China)  
PP-g-NHA and PP-g-NHA/St have been prepared via melt grafting by using a twin-screw extruder using dicumyl peroxide(DCP) as an initiator.FTIR confirmed the grafting of NHA and St onto polypropylene(PP) chains.The effect of the content of monomer,initiator,extrusion temperature,and screw speed on the grafting degree and the resulted contact angle of grafted PP was investigated.When the content of NHA was 3 %,the obtained grafting degree and contact angle were 1.6 % and 83 °,respectively.With increasing loading of DCP,the grafting degree increased and then decreased.The screw speed should be higher than 40 r/min.
