摘要
综述了利用哈克转矩流变仪及采用反应挤出法制备接枝聚合物的特点及接枝体系的选择。另外,以马来酸酐为例,阐述了接枝反应的机理,同时总结了几类可通过反应挤出进行接枝改性的聚合物,并对接枝聚合物的应用进行概括。关于接枝物的表征,主要从纯化方法、接枝的确定、接枝率的测定方法等方面进行了概述。
New methods of preparing novel polymer and modifying polymer are grafting of polymer by reactive extrusion and in the Haake torque rheometer. The characteristic of preparing graft polymer by above methods, and the compositoin which are chosen by certain rule are reviewed. In addition, mechanism of grafting is briefly introduced by maleic anhydride. A few kinds of grafted polymers, which are apposite to reactive extrusion are generalized. The application of the grafted polymer is also summarized. The methods of purification and determination of the graft yield are also summarized.
