| Description |
We have synthesized asymmetric di- and triblock copolymers containing chemically complementary blocks of poly(acrylic acid) and methoxypoly(ethylene oxide) (PAAc-b-MOPEO) or poly(ethylene oxide) (PAAc-b-PEO-b-PAAc) using a template radical block copolymerization process. At low pH, polyacid blocks of these copolymers were protonated and formed the intramolecular polycomplexes (IntraPCs) with MOPEO or PEO blocks. Due to both the intramolecular complex formation and hydrophobic interactions between non-polar bound segments of the blocks, an intensive micellization in copolymer solutions at low pH 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. |
