摘要
以马来酸酐作对照,用热分析、流变、化学分析等方法,研究了马来酸和衣康酸在非隔氧条件下与PP熔体催化接枝反应的特点和规律,阐述了单体结构-单元反应相对速率-接枝产物结构之间的关系,提出了3种接枝物的结构模型。
In contrast to maleic anhydride, the characteristics and laws of melt graft reaction of maleic acid and itaconic acid with PP in the presence of oxygen and peroxide were investigated by means of thermal analyses, rheology and chemical analyses,The relationships between monomer structurerelative rates of elementary reactions-graft resultant structure were discussed and the structural models of the three graft resultants were proposed.
