The objective of this study was to synthesize and characterize particles as a drug-delivery platform for gliomas, a highly advanced and invasive stage of brain tumor with poor prognosis. Poly(aminoethyl methacrylate-co-methyl methacrylate) particles were prepared by suspension polymerization and poly(aminoethyl methacrylate-co-poly(ethylene glycol) methacrylate) particles were prepared by emuls...

Terminally dibrominated poly(β-propiolactone) was prepared through sequentially ring-opening polymerization of β-propiolactone and dibromination the former product. Synthesis poly(β-propiolactone)-b poly(methyl methacrylate) tri-arm block copolymer achieved by atom transfer radical methyl methacrylate onto with bromide end groups. The characterization polymers carried out using 1H-NMR, DSC, TGA...

five new aromatic poly(amide-imide)s (5a-e) were synthesized by direct polycondensationreaction of n-(4-carboxy phenyl) trimellitimide (3) with five aromatic diamines (4a-e) by usingtriphenyl phosphite in n-methyl-2-pyrrolidone (nmp) and pyridine at solution containingdissolved cacl2. all of the polymers were obtained in quantitative yields with inherentviscosities between 0.29-0.40 dl/g. the r...

Considering the largely chiral nature of biological systems, there is interest in drug delivery systems. Here, we investigate for first time polymer micelles based on poly(2-oxazoline) (POx) ABA-type triblock copolymers with and racemic hydrophobic blocks formulation achiral drugs. Specifically, poly(2-ethyl-4-ethyl-2-oxazoline) (pEtEtOx) poly(2-propyl-4-methyl-2-oxazoline) (pPrMeOx) were used ...

A novel N-sulfonyl aziridine, N-((2-(trimethylsilyl)ethyl)sulfonyl)-2-methyl-aziridine (SES-MeAz) was synthesized, and its controlled anionic ring-opening polymerization to form poly(SES-MeAz) studied. The desulfonylation of poly(SES-MeAz)s can be achieved under mild conditions, with tetrabutylammonium fluoride (TBAF) polypropylene imine (PPI), although purification the PPI not completely succe...

Aqueous emulsion polymerization via reversible complexation mediated living radical yielded low-dispersity poly(methyl methacrylate)s and polystyrenes.

The production of open-cell (OC) nanostructures in polymer foams without non-foamed solid skins by gas dissolution foaming has been developed this work. First, several grades MAM block copolymer (methyl methacrylate-b-butyl acrylate-b-methyl methacrylate) at high content are employed as heterogeneous phase poly(methyl for producing OC structures. Atomic force microscopy and extensional rheology...
