| dc.description.abstract | The present thesis entitled “APPLICATION OF ATOM TRANSFER RADICAL POLYMERIZATION FOR THE PREPARATION OF MULTIFUNCTIONAL MATERIALS” deals with the controlled synthesis and application of different multifunction amphiphilic block and graft copolymers. The work is carried out at the department of chemistry, Presidency University, Kolkata 700073, India, under the supervision of Dr. Dhruba Prosad Chatterjee. The thesis comprises of five chapters. Chapter 1 deals with a brief introduction of classification and architectures of polymers and different techniques of polymerization. It also emphasizes the advantage of ‘living’ radical polymerization. This chapter provides an elaborate discussion of commercially attractive different LRP techniques with low metal mediated complex concentration. Chapter 2 deals with the synthesis of ‘living’ poly(2- dimethylaminoethyl methacrylate) by bulk atom transfer radical polymerization using CuCl/ N,N,N/ ,N/ ,N// -pentamethyldiethylenetriamine catalyst at ambient temperature which occurs through soluble ATRP catalyst entrapped within reverse micelles where an adventitious role of water molecules during polymerization is noted. Synthesized PDMAEMA molecules work efficiently as macroinitiators for the synthesis of different stimuli responsive, multifunctional di- or triblock copolymers through sequential polymerization. Chapter 3 deals with the stabilization of CdS quantum dots by the diblock copolymer PDMAEMA-bpoly[di(ethyleneglycol)methyl ether methacrylate] in aqueous medium which show stimuli dependent reversible switch between micelle ‘core-confined’ and ‘corona-embedded’ morphologies. Chapter 4 deals with the synthesis of different Poly(vinylidene fluoride) grafted amphiphilic random ter/bi- copolymers containing reactive Poly(furfuryl methacrylate) or thermo responsive PDEGMEM etc. as constituents by ATRP in homogeneous solution followed by the post polymerization modification with maleimide by the Diels-Alder reaction to introduce imidodicarbonyl moieties. Membrane fabrication is subsequently done by breath figure or immersion-precipitation techniques. The fabricated membrane offers the capability of exerting affinity-interaction with melamine or nucleobases in the protein immobilization. Chapter 5 deals with the future objective where synthesis of PVDF based graft copolymers having hydrophobic/hydrophilic stimuli responsive polymer systems effective in metal-ion affinity membrane chromatography along with the preparation v of block copolymers based on (2-hydroxyethyl) methacrylate chains which has an immense utility in the industrial and biomedical field has been proposed. | en_US |
