Abstract

The synthesis was performed of grafted copolymers of acrylic acid on low molecular weight polyethylene in the presence of benzoyl peroxide in o-xylene solution. The formation of copolymers was proved by the methods of functional analysis of carboxyl groups and FTIR spectroscopy. The patterns of synthesis are shown, which made it possible to obtain graft copolymers in a wide range of compositions. X-ray diffraction analysis demonstrated that the presence of acrylic acid units in the copolymer leads to a decrease in the crystallinity of the copolymers compared to the initial low molecular weight polyethylene.

丙烯酸与低分子量聚乙烯的接枝共聚物的合成与结构

摘要

二甲苯溶液中过氧化苯甲酰的存在下,丙烯酸在低分子量聚乙烯上的接枝共聚物的合成。通过羧基官能团分析和FTIR光谱法证明了共聚物的形成。显示了合成模式,这使得有可能获得多种组成的接枝共聚物。X射线衍射分析表明,与初始的低分子量聚乙烯相比,共聚物中丙烯酸单元的存在导致共聚物的结晶度降低。
