【摘要】 介绍用溶液法合成ＰＥ－ｇ－马来酰亚胺（ＭＩ），并研究它作为相容剂对ＰＥＴ／ＰＥ共混物热、力学性能和形态结构的影响。结果表明，在ＰＥＴ／ＰＥ共混体系中，加入少量ＰＥ－ｇ－ＭＩ，可较好地改善ＰＥＴ与ＰＥ之间的相容性，增加两相间的界面粘接力，同时对ＰＥＴ的结晶有较强的促进作用，使其冷结晶温度降低，并且即使在共混物的淬火过程中，ＰＥ－ｇ－ＭＩ也能很好地诱导ＰＥＴ结晶。更多还原

【Abstract】 s PE-g-Maleimide(MI) was synthesized by means of solution method,and the effects of the prepared PE-g-MI on thermal mechanical properties and morphological structure during blending of PET/PE were studied.The results showed a little amount of PE-g-MI could decrease the cold crystalline temperature rapidly of the blend,and induce PET to form big spherulites during the quenching process of PET/PE blend.It was shown by SEM that there was an intence interphase layer between PET continuous phase and PE discontinuous phase,and a filiform structure of PE discontinuous phase could be found on the impact fracture,indicating that PE-g-MI could improve the compatibility of PET with PE,increase the adhesivity of the two phases.更多还原
