中文摘要	compatibilization of blends of linear low-density polyethylene (lldpe)-poly(methyl methacrylate) (pmma) and lldpe-copolymer of methyl methacrylate (mma) and 4-vinylpyridine (poly(mma-co-4vp) with poly(ethylene-co-methacrylic acid) (emaa) have been studied. mechanical properties of the lldpe-pmma blends increase upon addition of emaa. in order to further improve interfacial adhesion of lldpe and pmma, 4-vinyl pyridine units are introduced into pmma chains, or poly(mma-co-4vp) is used as the polar polymer. in lldpe-poly(mma-co-4vp)-emaa blends, interaction of maa in emaa with 4vp of poly(mma-co-4vp) causes a band shift in the infrared (ir) spectra. chemical shifts of n-1s binding energy in x-ray photoelectronic spectroscopy (xps) experiments indicate a transfer of proton from maa to 4vp. scanning electron microscopy (sem) pictures show that the morphology of the blends were improved upon addition of emaa. nonradiative energy transfer (nret) fluorescence results attest that there exists interdiffusion of chromophore-labeled lldpe chains and chromophore-labeled poly(mma-co-4vp) chains in the interface. based on experimental results, the mechanism of compatibilization is studied in detail. compatibilization is realized through the interaction between maa in emaa with 4vp in poly(mma-co-4vp).
