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...

The paper evidences changes of thermal properties of poly(methyl methacrylate) as well as methyl methacrylate copolymers with glycidyl methacrylate (GMA) polymers synthesized classic and comparatively in a magnetic field. Samples of poly(methyl methacrylate) and methyl methacrylate copolymers with different amounts of GMA synthesized by radical emulsion polymerization with or without the presen...

atom transfer radical polymerization of styrene (st) and methyl methacrylate (mma) was performed at 90oc in the absence and presence of nanoclay (cloisite 30b). trichloromethyl-terminated poly(vinyl acetate) telomerand cucl/ pmdeta were used as a macroinitiator and catalyst system, respectively. the experimental results showed that the atom transfer radical polymerization of st and mma in the a...

AIMS AND OBJECTIVES To evaluate and compare the effect of fiber reinforcement on the dimensional changes of heat-cured poly (methyl methacrylate) resin after processing and immersion in water. MATERIALS AND METHODS Three different heat-cure resins were selected for the present study: (1) Nonreinforced heat-cure methyl methacrylate resin, (2) High Impact heat-cured methyl methacrylate resin an...

In this communication, we prepared carbon nanotubes (CNTs) modified by poly(vinyl alcohol) that are used as co-stabilizers for the dispersion polymerization of methyl methacrylate. Poly(methyl methacrylate) microspheres with CNTs selectively located at their surface are formed. This specific localization is a way to enhance the electrical conductivity of the nanocomposite.

The incorporation of self-assembled nanoparticles, a.k.a. hydroxylated nanoballs, into poly(2-hydroxyethyl methacrylate)(PHEMA) gives rise to a cross-linked network/hydrogel with enhanced interfacial interaction, whereas its inclusion in poly(methyl methacrylate)(PMMA) results in plasticization.

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...
