Modification of Polyvinyl Alcohol via Atom Transfer Radical Polymerization for Targeted Drug Delivery Applications
In current study,a hydrogel based on biocompatible polymerwas prepared. The functionalization of polyvinyl alcohol (PVA)with epichlorohydrin(ECH) to produce epichlorohydrin-g-polyvinyl alcohol (PVA/ECH) as a suitable macroinitiator for atom transfer radical polymerization (ATRP) reaction was investigated.ThenN-vinyl pyrrolidone (NVP) waspolymerized on the surface of macroinitiatorin presence of...
متن کاملkinetic study of atom transfer radical polymerization of methyl acrylate with polyvinyl acetate macroinitiator
in atom transfer radical polymerization (atrp) of methyl acrylate (ma) with polyvinyl acetate macroinitiator in bulk at 90°c the plots of ln [m]0/[m] increased linearly with reaction time. the apparent propagation rate constant (kp app) of the reaction was obtained from the linear curve and used to calculate the free macroradical concentration ([r°]) in polymerization medium. the [r°] and also ...

متن کاملMacromolecular engineering by atom transfer radical polymerization.
This Perspective presents recent advances in macromolecular engineering enabled by ATRP. They include the fundamental mechanistic and synthetic features of ATRP with emphasis on various catalytic/initiation systems that use parts-per-million concentrations of Cu catalysts and can be run in environmentally friendly media, e.g., water. The roles of the major components of ATRP--monomers, initiato...
متن کاملControlled grafting of acetylated starch by atom transfer radical polymerization of MMA
Graft copolymers of acetylated starch oligomer (AS) and poly(methyl methacrylate) (PMMA) were polymerized by atom transfer radical polymerization (ATRP). AS was converted to an ATRP macroinitiator by converting a part of the hydroxyl groups of AS to 2-bromoisobutyryl groups. Macroinitiators with varying degrees of substitution for the 2-bromoisobutyryl group were prepared. The polymerizations w...
