Abstract

Poli(4-vinilbenzil-g-stiren) [poli(VB-g-S)] aşı kopolimeri tersinir katılmalı/ayrışmalı zincir transfer (RAFT) ve serbest radikal polimerizasyon (FRP) teknikleri kullanılarak sentez edildi. Bu amaç için, 4-vinilbenzil klorür monomeri kullanılarak FRP yöntemiyle poli(4-vinilbenzil klorür) [poli-4-VBC] polimeri sentezlendi. İkinci aşamada, poli-4-VBC polimeri ile potasyum etil ksantat reaksiyona sokularak makro-RAFT ajanı oluşturuldu. Son aşamada, RAFT tekniğiyle makro-RAFT ajanı varlığında stiren monomeriyle poli(VB-g-S) aşı kopolimeri sentez edildi. Sentezlenen ürünler 1H-NMR, FT-IR, TGA, SEM ve Dinamik Işık Saçılım (DLS) cihazları gibi spektroskopik ve termal analiz teknikleri kullanılarak karakterize edildi.
