This contribution reviews plasma polymer nanoparticles produced by gas aggregation cluster sources either via plasma polymerization of volatile monomers or via radio frequency (RF) magnetron sputtering of conventional polymers. The formation of hydrocarbon, fluorocarbon, silicon- and nitrogen-containing plasma polymer nanoparticles as well as core@shell nanoparticles based on plasma polymers is...

Optically active polymers containing P-stereogenic bisphosphine and 1,2,3-triazole units in the main chain were obtained by copper-catalyzed Huisgen cycloaddition. The repeating unit of the polymer adopted bidentate as well as tetradentate coordination, leading to the change in the conformations of the polymer via complexation with transition metals.

Polymer film dosage forms of local anesthetics have been developed. Drug release from polymeric forms is investigated. Drug containing polymeric films shows a high initial release rate and the matrix-controlled release for more 6-8 h. The release data depends on drug loading and polymer structure. The possibility of application of polyvinyl alcohol for prolongation of anesthetics is show.

Rhodium(0) nanoparticles stabilized by a polymer containing carboxylate and β-cyclodextrin moieties have high stability and catalytic activity for aqueous hydrogenation reactions of olefins and aromatic substrates. This catalytic system can be recycled and reused without loss of activity. These high catalytic performances can be attributed to conjugated electrostatic interactions (carboxylate g...

Objectives: Assess the thermal and hydrolytic stability of patented macromer- based dental polymer matrices composites Methods: Polymer on a material (IP:343192) containing hybrid amorphous macromers co-polymerized with one 4 different dimethacrylates was prepared photo-thermal behavior were assessed. Diffusivity resistance cross-link density polymers Sorption (

The objective of this study was to formulate and evaluate the drug-polymer interaction of mefenamic acid (MA) using two polymers with different characteristics as ethylcellulose (EC) and/or cellulose acetate phthalate (CAP). Microspheres were prepared by the modified emulsion solvent evaporation (MESE). The effect of drug-polymer interaction was studied for each of microspheres. Important param...

A new theoretical model based on the local composition concept (TNRF-mNRTL model) was proposed to express the short-range contribution of the excess Gibbs energy for the solutions containing polymer and electrolyte. This contribution of interaction along with the long-range contribution of interaction (Pitzer-Debye-Hückel equation), configurational entropy of mixing (Flory-Huggins relation)...

The usefulness of pH-sensitive fusogenic polymer-(succinylated poly(glycidol)-(SucPG-) modified liposomes as a vaccine carrier in the induction of immune responses was evaluated. Mice were intraperitoneally immunized with ovalbumin- (OVA-) containing SucPG-modified liposomes. After immunization, significant OVA-specific antibodies were detected in the serum. When sera were analyzed for isotype ...

We describe a means of chemical amplification to accelerate triggered degradation of a polymer and particles composed thereof. We designed a light-degradable copolymer containing carboxylic acids masked by photolabile groups and ketals. Photolysis allows the unmasked acidic groups in the polymer backbone to accelerate ketal hydrolysis even at neutral pH.
