Abstract

This paper reports the investigation of copolymerization of acrylonitrile with methyl acrylate, dimethyl maleate, dimethyl fumarate and dimethyl itaconate via atom transfer radical polymerization mechanism using copper bromide as a catalyst in combination with tris(2-pyridylmethyl)amine as a ligand. The reactivity ratios of monomers were evaluated using the Finemann–Ross and Kelen–Tudos methods basing on the copolymer composition determined by ¹H NMR spectroscopy. It was found that reversible deactivation mechanism has no significant influence on the monomer reactivity ratios. It was found that among the tested comonomers methyl acrylate and dimethyl itaconate seem to be the most suitable ones for obtaining well-defined copolymers of acrylonitrile.

丙烯腈与不饱和甲基酯控制共聚中单体反应比的测定

摘要

本文以溴化铜为催化剂，结合三（2-吡啶基甲基）胺为配体，通过原子转移自由基聚合机理，研究了丙烯腈与丙烯酸甲酯，马来酸二甲酯，富马酸二甲酯和衣康酸二甲酯的共聚反应。基于¹ H NMR光谱测定的共聚物组成，使用Finemann–Ross和Kelen–Tudos方法评估单体的反应率。发现可逆失活机理对单体反应率没有显着影响。已经发现，在测试的共聚单体中，丙烯酸甲酯和衣康酸二甲酯似乎是最适合获得明确定义的丙烯腈共聚物的共聚物。
