Organic Syntheses Using Polymeric Supports, Polymeric Reagents, and Polymeric Catalysts

Journal of Macromolecular Science, Part C: Polymer Reviews, 1976
Abstract In conventional organic syntheses, organic molecules are treated with a reagent or reagents and the transformed organic molecules, now termed the product, are isolated. The various steps in a conventional organic synthesis may be represented schematically as in Fig. 1.

Supramolecular polymeric hydrogels

Chemical Society Reviews, 2012
The supramolecular crosslinking of polymer chains in water by specific, directional and dynamic non-covalent interactions has led to the development of novel supramolecular polymeric hydrogels. These aqueous polymeric networks constitute an interesting class of soft materials exhibiting attractive properties such as stimuli-responsiveness and self ...

Photocontrolled living polymerizations

Nature Materials, 2006
Living polymerizations involve the creation of polymer chains without significant irreversible chain transfer or chain termination. Such processes are widely used to access well-defined macromolecular materials with controlled architectures, such as block and star polymers.

Polymere Reagenzien, 5. Polymere Selenreagenzien

Die Makromolekulare Chemie, 1976
AbstractPolymere Selenreagenzien vermeiden die Schwierigkeiten, die bei der Handhabung von niedermolekularen Selenverbindungen durch Geruchsbelästigung und Toxizität vorhanden sind. Die Synthese von polymeren Reagenzien mit Selenophenol‐ und Diphenylselenoxidgruppen wird beschrieben.

Polymeric palladium-mediated carbene polymerization

Polymer Chemistry, 2015
A newly-developed metal-carbene radical polymerization mechanism is proposed for poly(imidazole-Pd)-mediated carbene polymerization, which could produce stereoregular polycarbenes besides atactic polycarbenes.

Stereospecific Polymerization of Dialkyl Muconates through Free Radical Polymerization:  Isotropic Polymerization and Topochemical Polymerization

Macromolecules, 1996
Radical polymerization of dialkyl muconates (dialkyl 2,4-hexadienoates) was investigated in an isotropic (amorphous) state, that is, solution or bulk polymerization, and in a crystalline state. In the bulk polymerization at 120 °C in the presence of a radical initiator, high molecular weight polymers of more than 105 were obtained in high yields ...

Radical Polymerization

2007
This volume from the successful Macromolecular Symposia series presents the contributions from the IUPAC-sponsored International Symposium on Radical Polymerization: Kinetics and Mechanism, held in Il Ciocco, Italy, in September, 2006. This was the fourth within the series of so-called SML conferences, which are the major scientific forum for ...

Frontal Polymerization: Polymerization Induced Destabilization of Peracrylates

Macromolecular Rapid Communications, 2011
AbstractFrontal photopolymerization has attracted much attention in the last decade as it allows the curing of thick films. Unfortunately, the use of peroxides, which feature appropriate storage stability, also requires inappropriately high initiation temperatures.
