【摘要】 星形聚合物是指三条以上线性聚合物支链以化学键连接于同一个核上所形成的超支化聚合物。与相同分子量的线性聚合物相比,其溶液粘度低、流体动力学半径较小,有望成为一种新型多功能的造纸助剂。论文介绍了星形聚合物的主要合成方法,并结合当前星形聚合物的应用研究现状,展望了其在造纸工业中的应用前景。更多还原

【Abstract】 Star-shaped polymers are high branched polymers consisting of multiple liner polymer arms attached to a core.They exhibit a smaller hydrodynamic radius and lower solution viscosity when compared to linear polymers of the same molecular weight and composition.Due to their special structure,the star-shaped polymers are believed to be new and effective aids for pulp and papermaking industry.The synthesis methods of star-shaped polymers were reviewed in this paper,and the outlook of their applications in papermaking industry was prospected.更多还原
