Bu çalışmada molce %5 ve %10 oranında p-klormetilstiren içeren poli(stiren-ko-p-klormetilstiren), p(St-koKMS),
stiren ve p-klormetilstiren monomerleri ile AIBN başlatıcısı varlığında serbest radikal polimerizasyonu
ile sentezlendi. Bu kopolimerin dietanolamin ve tris(hidroksimetil)aminometan ile ayrı ayrı modifikasyonuyla
sırasıyla, farklı oranlarda –OH yan grupları içeren poli[stiren-ko-p[bis(2-dihidroksietil)aminometil]stiren, p(Stko-DEAS)
ve poli[stiren-ko-p-tris(hidroksimetil)aminometil]stiren, p(St-ko-TMAS) elde edildi. Daha sonra
poli(stiren-ko-p-klormetilstiren)’in –OH uçları SOCl2 ile klorlanıp ardından tekrar dietanolamin ile
etkileştirilerek p(St-ko-p[bis(2,2-dihidroksiaminoetil)aminometil]stiren, p(St-ko-DAMS) sentezlendi. Elde
edilen kopolimerler FT-IR ve 1H-NMR ile karakterize edildi. Bütün polimerlerin oda sıcaklığında değişen
frekanslarda ve sabit frekansta artan sıcaklıkla impedans analizörle dielektrik sabitleri hesaplandı.
In this study, poly(styrene-co-p-choloromethylstyrene), p(St-co-CMS) containing 5% and 10% pchloromethylstyrene
was prepared by free radical polymerization of styrene and p-chloromethylstyrene
monomers in the presence of AIBN. This polymer was modified with diethanolamine and tris(hydroxymethyl)
aminomethane, respectively, and at poly [styrene-co-p-bis (2-dihydroxyethyl) aminomethyl styrene], p(St-coDEAS)
and poly[styrene-co-p-tris (hydroxymethyl) aminomethyl]styrene, p(St-co-TMAS) containing OH side
groups at different rates was obtained. Then –OH groups in poly(styrene-co-p-chloromethylstyrene) was reacted
with SOCl2 and was formed to chlorine groups in poly(styrene-co-p-chloromethylstyrene). Then it was reacted
with diethanolamine and was formed to p(St-co-p-bis(2,2-dihydroxyaminoethyl)aminomethyl)styrene, p(St-coDAMS).
The copolymers werw characterized by FT-IR and 1H-NMR. The dielectric properties of all the
copolymers were measured by different frequencies at room temperature and with increasing temperature at
constant frequency by impedance analyzer.
