Abstract

Bu çalışmada, ters atom transfer radikal polimerizasyonu (RATRP) metodu kullanılarak polietilen glikol (PEG) ve polimetil metakrilat (PMMA) bloklarını içeren çok dallı ya da çapraz bağlı kopolimerlerin sentezi gerçekleştirildi. Bunun için öncelikle, 4,4'-azobis(4-siyanopentanoik asit) ile fosfor pentaklorür reaksiyona sokularak 4,4'-azobis(4-siyanopentanoil klorür) (ACPC) elde edildi. Sentezlenen ACPC ile çeşitli molekül ağırlığına sahip PEG’ler (400 g.mol-1, 600 g.mol-1, 1000 g.mol-1, 1500 g.mol-1 ve 2000 g.mol-1) reaksiyona sokularak uç kısımlarında polietilen glikol içeren poliazoesterin (PAE) sentezi gerçekleştirildi. Elde edilen PAE ile metakriloil klorürün tepkimesinden metakriloil son uçlarına sahip polietilen glikol azoesterin (PAE-dimetakrioil) eldesi yapıldı. Ayrıca PAE ile 4-vinil benzil klorürün tepkimesinden 4-vinil benzil son uçlarına sahip polietilen glikol azoesterin (PAE-diVB) eldesi başarıldı. Son olarak PAE-dimetakrioil ve PAE-diVB kullanılarak metil metakrilatın RATRP ile çok dallı ya da çapraz bağlı kopolimerler sentezlendi. Sentezlenen ürünler FT-IR, 1H-NMR ve şişme değerleri (qv) teknikleri ile karakterilize edildi.

Synthesis and Characterization of The Hyper-Branched or Cross-Linked Copolymers Including Polyethylene Glycol and Polymethyl Methacrylate by Reverse Atom Transfer Radical Polymerization Method

Abstract

In this study, the synthesis of hyper-branched or cross-linked copolymers containing polyethylene glycol (PEG) and polymethyl methacrylate (PMMA) blocks was carried out using the reverse atom transfer radical polymerization (RATRP) method. For this, firstly, 4,4'-azobis (4-cyanopentanoic acid) was reacted with phosphorus pentachloride to obtain 4,4'-azobis (4-cyanopentanoyl chloride) (ACPC). By reacting PEGs of various molecular weights (400 g.mol-1, 600 g.mol-1, 1000 g.mol-1, 1500 g.mol-1 and 2000 g.mol-1) and synthesized ACPC, the synthesis of the polyazoester containing polyethylene glycol end groups (PAE) was carried out. By reacting obtained PAE and methacryloyl chloride, polyethylene glycol azoester possessing methacryloyl end groups (PAE- methacryloyl) was obtained. Additionally, it was achieved to obtain polyethylene glycol azoester with 4-vinyl benzyl end groups (PAE-diVB) from the reaction of 4-vinyl benzyl chloride with PAE. Finally, hyper-branched or cross-linked copolymers were synthesized by RATRP of methyl methacrylate using PAE- methacryloyl and PAE-diVB. The synthesized products were characterized by FT-IR, 1H-NMR, and swelling value (qv) techniques.
