Polymer-bound benzoin ether photoinitiators.

Free radical macrophotoinitiators: an overview on recent advances

This paper provides an overview of the recent advances on polymeric photoinitiators for UV curing. During the last decade, significant developments have been achieved in the synthesis of macrophotoinitiators, due to the advantages derived of their macromolecular nature, in comparison with their corresponding low molecular weight analogues. In particular, a variety of macromolecules containing t...

Polymer Bound Elastase Inhibitors

Polymer - bound osmium oxide catalysts ’

Polymer-supported oxidic osmium catalysts based on cross-linked poly(4-vinyl pyridine) were synthesized by various routes and characterized by a number of physical techniques (Raman, IR, XPS, “C and 15N solid-state NMR spectroscopy). Model compounds of type Os,O,L, (L = pyridine, 4-iso-propyl pyridine, and 4-tert-butyl pyridine) were obtained under the conditions of the catalyst synthesis. The ...

Multiple use of benzoin as an aid in neurosurgical practice: the watertight benzoin dressing.

The author presents a survey of his experience with the use of benzoin as an aid to prevent and to treat wound complications as: CSF leakage ruptured meningoceles, prevention of leakage and wound infections, during the use of external cranial drainage, indwelling catheters or implanted cannulas and electrodes. A few other handy uses are also mentioned.

High performance polymer particles for composite matrices: poly(arylene ether ether sulfide)s*

A method has been developed for the synthesis of semicrystalline poly(arylene ether ether sulfide) materials by first preparing a soluble, amorphous sulfoxide containing precursor, then rapidly reducing the sulfoxide moiety to sulfide. The sulfoxide polymers are synthesized using conventional nucleophilic aromatic substitution reactions between difluorodiphenyl sulfoxide and diphenols. Reductio...
