Poly[2-(diethylamino ethyl methacrylate)] (PDEAEM) and its ethylene glycol
dimethacrylate (EGDMA) cross-linked hydrogels were synthesized by free radical
polymerization. Chemical structure was characterized by FTIR spectroscopy. The
morphology of the homopolymer and of the hydrogels was investigated by SEM
analysis. Swelling properties of the EGDMA crosslinked hydrogels of PDEAEM
were followed under acidic and neutral conditions. The results revealed weakly pH
responsive swelling behaviour with equilibrium swelling capacity values of 50% in
acidic medium and 30% in distilled water. The drug loading and delivery properties
of the homopolymer and its hydrogels were investigated using ciprofloxacin HCl as
the model compound. EGDMA crosslinked hydrogels of PDEAEM exhibited 35%
CFX loading capacity at pH=4 in 72 h. A percent cumulative drug release value of
60 was obtained with the hydrogel that (DEAEM/EGDMA = 1:7.5 by mole) within 2
hours in acidic solution.
Keywords: 2-(diethylamino ethyl methacrylate), ethylene glycol dimethacrylate,
hydrogels, ciprofloxacin-HCl, potassium persulfate, free radical polymerization. |

ÖZ :
Bu çalışmada poli[2-(dietilamino etil metakrilat)] (PDEAEM) homopolimer ve onun
etilen glikol dimetakrilat (EGDMA) ile çapraz bağlanmış hidrojellerinin sentezi ve
karakterizasyonu incelenmiştir. Polimerler serbest radikal polimerleşmesi yöntemi ile
çözelti içinde azot ortamında sentezlenmiştir. Ürünlerin kimyasal yapısı FTIR
spektroskopisi ile, morfolojisi ise SEM analizi yöntemi ile belirlenmiştir. Ürünlerin
şişme davranışları asidik ortamda ve saf suda takip edilmiştir. Asidik ortamda %50,
saf suda ise %30 oranında ağırlıkça şişme saptanmıştır. Bu durumda hidrojellerin
zayıf da olsa pH’a bağlı şişme davranışı gösterdikleri anlaşılmıştır. Homopolimerin
ve hidrojellerin ilaç hapsetme ve ilaç salım özellikleri ciprofloxacin HCl antibiyotik
ilaç model alınarak araştırılmıştır. EGDMA ile çapraz bağlanmış PDEAEM
hidrojellerin pH=4 çözelti içinde 72 saat sonunda %35 CFX yüklenme kapasitesine
sahip olduğu ve (DEAEM/EGDMA = 1:7.5 mol oranı) hidrojel örneğinin hapsedilen
ilacın %60’ını asitli ortamda 2 saat içinde saldığı belirlenmiştir.
Anahtar Kelimeler: 2-(dietilamino etil metakrilat), etilen glikol dimetakrilat,
hidrojel, siprofloksasin-HCl, potassium persülfat, serbest radikal polimerleşme. |
