Determination of Reactivity Ratios for Acrylonitrile/Methyl Acrylate Radical Copolymerization Via Nonlinear Methodologies Using Real Time FTIR
Reactivity ratios for the homogeneous free radical initiated copolymerization of acrylonitrile and methyl acrylate were measured by NMR on isolated, low conversion copolymers and by real time in situ FTIR. The system utilized azobisisobutyronitrile (AIBN) initiator in dimethyl formamide (DMF) at …

Synthesis and Characterization of Responsive Poly(Alkyl Methacrylate) Topologies
… with methyl methacrylate via solution free-radical copolymerization. The styrene blocks in the purified graft copolymers were selectively sulfonated using acetyl sulfate.

The Chemistry of Dimethacrylate-Styrene Networks and Development of Flame Retardant, Halogen-Free Fiber Reinforced Vinyl Ester Composites
… endgroups cure with styrene via free radical copolymerization to yield thermoset networks. The copolymerization behavior of these networks was monitored by Fourier Transform Infrared Spectroscopy (FTIR) at various cure conditions. Reactions of the carbon-carbon double bonds of the …

Effects of Functionality and Charge in the Design of Acrylic Polymers
… pseudo first order rate kinetics for random copolymerizations. Protection of the hydroxyl using trimethylsilyl chloride alleviated isolation issues of amphiphilic polymer products. For the first time zwitterion-containing copolymers were electrospun to form nanoscale fibers with diameters as …

Development of Polymeric Nanocarriers for Dual Magnetic Resonance Imaging and Drug Delivery
… The graft copolymers were prepared by free radical copolymerization of ammonium bisphosphonate methacrylate monomers with PEO-acrylate macromonomers. The complexes exhibited good colloidal stability without release of free manganese and did not show any in vitro toxicity against mouse …

Sterically Crowded Copolymers Based on Functionalized Stilbenes
… comonomer pairs and the alternating copolymerization of these comonomers lead to precise control over charge density and placement of charged groups along the polymer backbone. Analogous styrenic copolymers, for direct comparison to the stilbene structures, were also prepared. Broad …

Design of Functional Polyesters for Electronic and Biological Applications
… to linear liquid crystalline copolyesters, copolymerization with oligomeric hydroxyl-functionalized polyethers afforded segmented liquid crystalline copolyesters. 4,4’-Biphenyl dicarboxylate (BDE), commercially available diols containing 4, 5, 6, 8, or 10 methylene units, and introducing …
