Block Copolymers Containing Poly(acrylic acid) for Stabilization of Vitamin E and Silver Nanoparticles in Aqueous Solutions

摘要

We have synthesized asymmetric di- and triblock copolymers containing chemically complementary udblocks of poly(acrylic acid) and methoxypoly(ethylene oxide) (PAAc-b-MOPEO) or poly(ethylene oxide) ud(PAAc-b-PEO-b-PAAc) using a template radical block copolymerization process. At low pH, polyacid blocks udof these copolymers were protonated and formed the intramolecular polycomplexes (IntraPCs) with udMOPEO or PEO blocks. Due to both the intramolecular complex formation and hydrophobic interactions udbetween non-polar bound segments of the blocks, an intensive micellization in copolymer solutions at low udpH took place. Aqueous copolymer solutions were used as nanocontainers for encapsulation of poorly soluble vitamin E and as nanoreactors for the silver nanoclusters/nanoparticles formation.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/34943
