【摘要】 <正> The compatibility of blends of MS copolymer and MS-g-PBd has been studied. MS copolymers have been cross-fractionated and characterized. The transparent electron microscope study shows that the compatibility of blends would be stepwise improved with the decrease in M. W. ratios of MS copolymer to g-MS. Under the same conditions, an increase in M content and M unit sequence length of MS in the blends favours the compatibility between the MS copolymer and MS-g-PBd.更多还原
