introduction bolus is a soft and resilient material which is used for increasing skin dose or to even out the irregular patient contour. the main property of various materials used presently as bolus is the water-equivalent electron density. ethyl methacrylate is used as a soft-liner in dentistry and its physical and chemical properties are proved to be nontoxic for human body. the goal of this...

Poly((2edimethylamino)ethyl methacrylate) with 60,000 g/mol and a narrow polydispersity (1.12) was synthesized using group transfer polymerization in order to investigate the structure of poly ((2edimethylamino)ethyl methacrylate)/sodium dodecylsufate complexes in water. The synthesized polymer chain conformation in water was studied as a function of deuterated sodium dodecylsulfate concentrati...

The 2-(2-methoxyethoxy)ethyl methacrylate and molecular oxygen react at 50 °C under high pressure in the presence of a radical initiator to give water soluble, thermoresponsive poly(2-(2-methoxyethoxy)ethyl methacrylate) peroxide (PMEO(2)MAP), which degrades highly exothermically. The polymer structure has been confirmed by spectroscopy, elemental analysis, calorimetry and mass spectrometry.

graft polymerization of acrylic acid (aa) and ethyl methacrylate (ema) onto starch (st) were carried out in aqueous solution using ceric ammonium nitrate (can) as redox system under n2 atmosphere. the effect of ph, reaction time, temperature, concentrations of can, st, and monomers on the graft yield was investigated. monomer reactivity was in the following order: aa>ema.the kinetics of the gra...

Antioxidant capacity of poorly soluble natural antioxidant kaempferol, in particular free or loaded two types cationic micelles, was studied on non-enzyme induced lipid peroxidation (LPO) vitro . The micelles were based triblock copolymers - poly(2-(dimethylamino)ethyl methacrylate-b-poly(propylene oxide)-b-poly(2-(dimethylamino)ethyl methacrylate (PDMAEMA-PPO-PDMAEMA) and methacrylate-b-poly(ε...

Polymers containing poly(ethylene glycol) methacrylate and 2-(2-methoxyethoxy)ethyl methacrylate have been synthesized by Cu(0)-mediated radical polymerisation for use as thermoresponsive water-dispersants for carbon nanotubes.

Novel enzyme-mediated synthetic routes were developed to provide a new family of sophorolipid derivatives and glycolopid-based amphiphilic monomers. These compounds are of great interest for their potential use in immunoregulation, as well as for other biological properties. In the present work, an efficient lipase-catalyzed conversion of sophorolipid ethyl ester to (a) the 6'-monoacylated deri...

The use of self-assembled nanoparticles for drug delivery has received significant attention in recent years. However, the dynamic nature polymeric systems means there is a need to develop greater understanding inherent stability these systems. In particular, if materials remain as discrete nanoparticles, or exchange material between particles critical. Herein, we labelled pH-responsive with fl...
