| 摘 要： | 我们用固体NMR方法研究了SAN与结晶PMMA的相容性,并提出了可能的相容性机理;同时我们也研究了PMMA的结晶行为,发现它不同于SMA/PMMA中只存在少量结晶区的PMMA的行为.SAN/结晶PMMA是部分相容的体系,由于PMMA中的羰基与SAN中的苯基的相互吸引才导致共混物相容,且SAN只与无定形PMMA区相容,结晶区可用NMR方法检测到,这说明SAN/PMMA的相容性比SMA/PMMA差,主要原因是SAN与PMMA的相互作用弱于SMA与PMMA的相互作用.交替共聚利于相容.

| Abstract: | The miscibility of SAN/PMMA blends and the crystallization behavior of PMMA have been studied by NMR means. The results indicate that there exists pronounced crystalline phase in partly miscible SAN/PMMA blends, and most of miscible phase evince the character of interfacial domain. These are different from miscible SMA/PMMA blends. |
