Synthesis of some network polymers with siloxane units as a drug delivery system
New biodegradable network polymers containing siloxane-linked polymeric prodrugs of 5-ammino-2-hydroxybenzoic acid (5-ASA) in the main chain were prepared by ter polymerization of methacrylic acid (MA), 2-hydroxyethylmethacrylate (HEMA), and bis (trimethylsilyloxy) methylsilane (VBM) in the presence of some new cross-linking agents.The monomers and polymers were characterized by FT-IR and 1H-NM...

متن کاملEffect of volume changes on segmental relaxation in siloxane polymers.
From dielectric relaxation and equation-of-state measurements on polymethylphenylsiloxane and polymethyltolylsiloxane, the relative contributions of volume and thermal energy to the temperature dependence of the segmental relaxation times are quantified. In both polymers, volume exerts a substantial effect, being almost as significant as thermal energy. A possible consequence of this prominent ...
متن کاملSynthesis and characterization of poly(3-hexylthiophene)-functionalized siloxane nanoparticles.
Poly(3-hexylthiophene)-functionalized siloxane nanoparticles were prepared by a modified Stöber method. The photovoltaic performance of P3HT-nanohybrids with C60 derivative PCBM was evaluated. The device made from 1 : 1 blends of P3HT-NPs:PCBM showed reasonably good photovoltaic performance with a power conversion efficiency of 2.5% under standard test conditions (AM 1.5G, 100 mW cm(-2)).
