This study contains chemical modification of polystyrene with isobutyric
anhydride in Lewis acid catalyst [BF3.O(C2H5)2]
environment. It has been used Friedel-Crafts reactions for modification. The
determined optimum condition was used for this reactions. Modified polystyrene
containing acyl group has been modified with cyclohexyl isocyanate in the
presence of n-BuLi catalyst for the second time. The molecular structure of
polystyrenes containing acyl and amide groups obtained by these reactions was
clarified using spectroscopic methods and the amount of carboxyl group bound to
polystyrene as a result of modification was determined as volumetric. In
addition, second modification yields were determined according to the results
of elemental analysis. In each of the 6 styrene units in the new type of
polystyrene chain containing different functional groups, 3 of them had amide
functional group, 1 had acyl functional group and 1 had no functional group.
Both functional groups that bind to polystyrene will contribute to further
expansion of the application areas of polystyrene.

Bu çalışmada ilk olarak
polistirenin izobutirik anhidrit ile BF3.O(C2H5)2
Lewis asidi katalizörü ortamındaki kimyasal modifikasyonu gerçekleştirilmiş ve
modifikasyon için Friedel-Crafts reaksiyonlarından faydalanılmıştır. Bu
reaksiyon için önceden belirlenen optimum şart kullanılmıştır. Sentezlenen açil
grup içeren modifiye polistiren, siklohekzil izosiyanat ile n-BuLi katalizörü
varlığında ikinci kez modifiye edilmiştir. Elde edilen açil ve amit grup içeren
polistirenlerin yapısı spektroskopik yöntemler kullanılarak aydınlatılmış,
modifikasyon sonucu polistirene bağlanan karboksil grubu miktarı volumetrik
olarak belirlenmiştir. Ayrıca elementel analiz sonuçlarına göre de ikinci
modifikasyon verimleri tespit edilmiştir. Farklı fonksiyonel gruplar içeren
yeni tür polistiren zincirindeki her 6 stiren biriminden 3 tanesinde amit fonksiyonel
grubu, 1 tanesinde açil fonksiyonel grubu bulunan ve 1 tanesinde de hiçbir
fonksiyonel grup bulunmamaktadır. Polistirene bağlanan farklı her iki
fonksiyonel grubun polistirenin uygulama alanlarının daha da genişletilmesine
katkısı olacaktır.
