Traditional solution acrylic polymers for pressure sensitive adhesives (PSA) are synthesized using conventional free radical initiation systems based upon organic peroxide or azo compounds 1 . Such syntheses are heat activated and employ solvent reflux temperatures during the polymerization process. The resulting acrylic polymers are formed with a relatively broad molecular weight distribution ...

α-Fluoroalcohols have been proposed as transparent, base-soluble functional groups for use in the design of new 157 nm photoresist polymers. The two most common and easily prepared fluoroisopropanol groups are bis-trifluoromethyl carbinols (hexafluoroalcohol) and methyl-trifluoromethyl carbinols (trifluoroalcohol). This paper describes studies designed to assess the suitability of both of these...

The field of ocular drug delivery is one the most interesting and challenging fields for Formulation Scientists or Pharmacists. In ophthalmic in situ gel many polymers are used which form by various mechanisms like pH-sensitive thermo sensitive gel. We can make instead an solution to overcome problem low bioavailability. Some common diseases cured blepharitis, conjunctivitis, keratitis, trachom...

A novel triarylboron compound, MPB, exhibiting reversible thermochromic dual-fluorescence in solid-state polymers and in liquid solvents was designed and synthesized. The fluorescent solid-state polymer with MPB can serve as a highly sensitive self-reference temperature indicator with a concentration independent feature.

By combining the sensitivity of fluorescent units with the response of "smart" polymers to environmental changes, we propose a new approach for chemical detection applications. The system proved to be sensitive to 12 ppb of diethyl chlorophosphate (DCP), a Sarin surrogate, and to discriminate between the interfering molecules.

This paper reviews current state-of-the-art methods of measuring pH levels that are based on polymer materials. These include polymer-coated fibre optic sensors, devices with electrodes modified with pH-sensitive polymers, fluorescent pH indicators, potentiometric pH sensors as well as sensors that use combinatory approach for ion concentration monitoring.

A visible light-cleavable polymer is synthesised to overcome the limitations of UV-sensitive polymers. Photocleavable BODIPY functionalized with an ATRP initiator and alkyne was used to obtain an amphiphilic block copolymer by conducting the click reaction and polymerization simultaneously. Micellar assembly of the polymer was disintegrated under visible light irradiation with controlled releas...

The bis(pyrene) conjugated pH-sensitive polymers () were synthesized and self-assembled into nanoparticles through hydrophobic interactions. The Nile red (NR) loaded nanoparticles showed red emission due to the FRET effect. The nanoparticles entered cells via endocytosis, and the microenvironmental pH in the endocytosis process was monitored in situ by the simultaneous dual-wavelength fluoresce...
