Abstract

                Poli
(akriloilmorfolin-co-2-hidroksietil metakrilat) geleneksel serbest radikal
polimerizasyonu ile hazırlandı. Akriloilmorfolin (ACM) ve 2-hidroksietil
metakrilat (HEMA) monomerleriyle kopolimerizasyon, başlatıcı olarak
2,2'-azobisizobutironitril (AIBN) kullanılarak 60 ° C'de tetrahidrofuran
çözeltisi içinde gerçekleştirildi. Kopolimerler, FT-IR, 1H ve 13C nükleer
manyetik rezonans (NMR) ile karakterize edildi. Kopolimerlerin monomer
bileşimleri, elemental analizin azot sonuçlarıyla tahmin edildi. Kopolimerdeki ACM(r₁) ve HEMA(r₂)
monomerlerinin reaktivite oranları, çeşitli yöntemlerle hesaplandı. Bu
yöntemlere göre, r₁ değeri 1.73-2.01 ve r₂ değeri
0.48-0.74'tür. Kopolimerlerin termal özelliklerini
araştırmak için Termogravimetrik analiz kullanıldı.

RADICAL COPOLYMERIZATION OF ACRLOYLMORPHOLINE WITH 2-HYDROXYETHYL METHACRYLATE: MONOMER REACTIVITY RATIOS AND THERMAL PROPERTIES

Abstract

                Poly (acryloylmorpholine -co-
2-hydroxyethyl methacrylate) were prepared by traditional free radical
polymerization. Copolymerization with acryloylmorpholine(ACM) and
2-hydroxyethyl methacrylate(HEMA) monomers were carried out in tetrahydrofuran
solution at 60^oC using 2,2'-azobisisobutyronitrile(AIBN) as
initiator. The copolymers were characterized by FT-IR , ¹H and  ¹³C nuclear magnetic resonance
(NMR). Monomer compositions of  the
copolymers were established by nitrogen results of elemental analysis. The reactivity ratios of monomers ACM(r₁) and
HEMA(r₂) in the copolymer were calculated by various methods.
According to these methods, r₁ was 1.73-2.01 and  r₂ was 0.48-0.74. Thermogravimetric analysis was used to investigate the
thermal properties of copolymers.
