Poli - [(e-kaprolakton-b-epiklorohidrin-b-e-kaprolakton)] - g- (polistiren -) [(PCL-b-ECH-b-PCL)] - g-PS blok-asi kopolimerleri katyonik, halka aciklama polimerizasyonu (ROP) ve atom transfer radikal polimerizasyon (ATRP) tekniklerinin kombinasyonu ile sentezlenmistir. Bu amacla, epiklorohidrin (ECH) polimerize etmek icin katyonik halka acma teknigi kullanilmistir. Sentezlenen, Hidroksil fonksiyonel gruplu poli (epiklorohidrin) (PECH), e-kaprolaktonun (e-CL) 110 ° C’de halkali acilma polimerizasyonunun (ROP) baslaticisi olarak poli (e-kaprolakton-b-epiklorohidrin- B-e-kaprolakton) (PCL-PECH-PCL) blok kopolimerinin eldesinde kullanildi. Son olarak, baslatici olarak PCL-PECH-PCL’nin PECH blogunun klorometil gruplarini kullanarak gerceklestirilen stirenin atom transfer radikal polimerizasyonu (ATRP), [PCL-b-PECH-b-CL] -g-PS-graft kopolimeri olusumuyla sonuclanmistir. Elde edilen sonuclar, graft kopolimerlerinin molekuler agirliklarinin stiren donusumuyle arttigini gosterdi. Polimerler, 1 H-NMR, GPC ve DSC teknikleri ile karakterize edildi.
