Abstract

This study presents for the first time in the literature the polymerization of poly (ethylene glycol) methyl ether methacrylate Mn = 300 g/mol (PEGMA 300) in the presence of poly chloroethyl methacrylate-polymethylmethacrylate copolymer poly (CLEMA-MMA) that takes place by both the SARA-ATRP and SET-LRP mechanisms. The two types of polymerizations in the system are poly (PEGMA 300) grafting to the poly (CLEMA-MMA) backbone and forming a new poly (PEGMA 300), both happening in the presence of a Cu⁰ wire. Polymerization reactions are controlled, as confirmed by the molecular weight evolution with the conversion, the polymerization kinetics, the possibility to obtain block-copolymers, and the narrow value of dispersity.

The results demonstrated that the poly (PEGMA 300) grafting on the poly (CLEMA-MMA) polymer follows a SARA-ATRP mechanism, while the formation of a poly (PEGMA 300) homopolymer entails a SET-LRP process. The investigation methods used to highlight the two mechanisms were GPC, ¹HRMN, and UV-VIS-NIR.

PEGMA 300接枝反应中SARA-ATRP和SET-LRP共存机制的证实

本研究在文献中首次提出了聚（乙二醇）甲基丙烯酸甲醚Mn=300g/mol （PEGMA 300）在聚甲基丙烯酸氯乙酯-聚甲基丙烯酸甲酯共聚物聚（CLEMA-MMA）存在下，通过SARA-ATRP和SET-LRP机制进行聚合。系统中的两种聚合类型是聚（PEGMA 300）接枝到聚（CLEMA-MMA）主链和形成新的聚（PEGMA 300），两者都发生在Cu0线存在的情况下。聚合反应是可控的，这可以从分子量随转化率的变化、聚合动力学、获得嵌段共聚物的可能性和较窄的分散度值等方面得到证实。结果表明，聚（PEGMA 300）在聚（CLEMA-MMA）聚合物上接枝遵循SARA-ATRP机制，而聚（PEGMA 300）均聚物的形成则遵循SET-LRP过程。采用GPC、1hrrmn和UV-VIS-NIR三种研究方法来突出这两种机制。
