摘要

<正> The effects of magnetic field on the graft ratio and stereoregularity of grafts of PVA-g-MMA in the presence ofbenzophenone during UV irradiation are discussed. By means of IR

it was found that the graft ratio was increased with the increment of magnetic field strength. Furthermore

application of relative weak magnetic field of 0.4 Tesla had been shown to substantially enhance the stereo-regularity of graft copolymer. The maximum stereo-regularity appeared when the graft ratio approached to 85% with the magnetic field of 1.2 Tesla （T）. The resistance to moisture and heat resistance of the grafted copolymer in the presence of magnetic field were also improved.
