中文摘要	a reactive type nonionic surfactant, monostearic acid monomaleic acid glycerol diester (mmgd) was synthesized in our laboratory. grafting-copolymerization of linear low density polyethylene ( lldpe) with mmgd was carried out by using beta ray irradiation in air in a twin-screw extruder. evidence of the grafting of mmgd as well as its extent was determined by fourier-transformed infrared (ft-ir) spectroscopy. the effects of monomer concentration, reaction temperature and screw run speed on degree of grafting were studied systematically. the thermal behavior of lldpe-g-mmgd was investigated by using differential scanning calorimety ( dsc). compared with neat lldpe, the crystallization temperature ( tc) of lldpe-g-mmgd increased about 3 degrees c, and the melting enthalpy (delta h-m) decreased with increase of mmgd content. it showed that the grafted mmgd monomer onto lldpe acted as a nucleating agent. the tensile properties and light transmission of blown films were determined. comparing with neat lldpe film, no obvious changes could be found for the tensile strength, elongation at break and right angle tearing strength of lldpe-g-mmgd film. the wettability is expressed by the water contact angle. with an increasing percentage of mmgd, the contact angles of water on film surface of lldpe- g-mmgd decrease monotonically.
