【摘要】 研究了用红外光谱法分析 AN/VAc/MAS的共聚物组成及序列分布,比较了 AN/VAc与 AN/MA共聚物质序列分布。研究表明:共聚物中VAC含量低于10％时,大分子主键上VAc-VAc键接的可能性很小,说明了 VAc单元比较均匀地分布在大分子主键上,这对于纤维性能的均一稳定非常有利。第二单体VAc代替MA完全可行。更多还原

【Abstract】 The copolymer of AN/VAc/MAS is prepared by using dispersion precipitation copolymerization. The component and sequence structure of AN/VAc/MAS have been investigated by means of IR spectral analysis. Their IR spectra have been compared with those of AN/VAc and AN/MA. The results show that the component of VAc is distributed in the molecular main chain and the properties is benefited.更多还原
