中文摘要	a novel nonionic surfactant, glycerol monostearic acid monomaleic acid diester (gmmd) was synthesized in our laboratory. grafting-copolymerization of linear low density polyethylene (lldpe) with gmmd was carried out by using p-ray irradiation in a twin-screw extruder. evidence of the grafting of gmmd, as well as its extent, was determined by ft-ir. the effects of monomer concentration, reaction temperature and screw run speed on degree of grafting were studied systematically. the thermal behavior of lldpe-g-gmmd was investigated by using differential scanning calorimety (dsc). compared with neat lldpe, the crystallization temperature (t,) of lldpe-g-gmmd increased about 3 degrees c, and the melting enthalpy (delta h-m) decreased with increase of gmmd content. it showed that the arafted gmmd 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-gmmd film. accelerated dripping property of film samples was investigated. the dripping duration of lldpe-g-gmmd film and commercial anti-fog dripping film at 60 degrees c were 52 days and 17 days, respectively.
