Block copolymers

Amphiphilic hydrogels with different molecular architecture were successfully synthesized by two methods: (1) Williamson ether synthesis with linear or hyperbranched poly [(p-chloromethyl) styrene], PPCMSt and poly(ethylene glycol), PEG, and (2) nucleophilic substitution reactio…

This thesis reports the preparation of novel multi-responsive and multiply stimulable triblock copolymers. The resultant polymers were used to coat cotton fabrics and glass to render them amphiphobic. Further, a method was developed for the preparation of poly(ethylene glycol)- …
