Synthesis and characterization of some polyurethanes and polyurethane-ureas
Polyurethanes and polyurethane-ureas were prepared by the reaction of diethylene glycol and polyethylene glycol with excess of aromatic and aliphatic diisocyanate to yield isocyanate terminated prepolymers which were subsequently reacted with diols and diamines. These polymers were characterized by IR, 1HNMR spectra, viscosity measurements and thermogravimetric analysis.
متن کاملSynthesis of Poly(di[methylamine]ethyl methacrylate)-b- Poly(cyclohexyl methacrylate)-b-Poly(di[methylamine] ethyl methacrylate) Amphiphilic Triblock Copolymers by ATRP: Condensed-phase and Solution Properties
The synthesis of amphiphilic triblock copolymers, poly(di[methylamine]ethyl methacrylate)-b-poly(cyclohexyl methacrylate)-b-poly(di[methylamine]ethyl methacrylate) PDMAE-b-PCH-b-PDMAE, has been performed by atom transfer radical polymerisation. Those have been obtained in a well-controlled manner in terms of molecular weight and polydispersity index. The triblock copolymer characterisation has ...
متن کاملAssociation Behavior of Poly (methyl methacrylate-b-methacrylic acid-b-methyl methacrylate) in Aqueous Medium
ABA type tri-block amphiphilic polyelectrolyte consisting of poly(methyl methacrylate-block-methacrylic acid-block-methyl methacrylate) (P(MMA-b-MAA-b-MMA)) was synthesized by atom transfer radical polymerization technique (ATRP) and the self-assembly behavior of the polymers in aqueous solution was studied over the course of neutralization. Combination of potentiometric and conductometric tit...
متن کاملNanomechanical properties of solvent cast polystyrene and poly(methyl methacrylate) polymer blends and self-assembled block copolymers
The nanomechanical properties of solvent-cast polymer thin films have been investigated using PeakForceTM Quantitative Nanomechanical Mapping. The samples consisted of films of polystyrene (PS) and poly(methyl methacrylate) (PMMA) obtained after the dewetting of toluene solution on a polymeric brush layer. Additionally, we have probed the mechanical properties of poly(styrene-b-methyl methacryl...
متن کاملSelf-assembly of pODMA-b-ptBA-b-pODMA triblock copolymers in bulk and on surfaces. A quantitative SAXS/AFM comparison.
The phase state of a series of poly(n-octadecyl methacrylate)-b-poly(tert-butyl acrylate)-b-poly(n-octadecyl methacrylate) (pODMA-b-ptBA-b-pODMA) triblock copolymers, synthesized through atom transfer radical polymerization, has been investigated in bulk and on surfaces using small-angle X-ray scattering and atomic force microscopy, respectively. The mean-field theory was employed to construct ...
