Site-isolated porphyrin catalysts in imprinted polymers

Kay Severin, Corinne Daguenet, Estelle Burri

A meso-tetraaryl ruthenium porphyrin complex having four polymerizable vinylbenzoxy groups (2) has been synthesized by reaction of pyrrole with 4-(vinylbenzoxy)benzaldehyde and subsequent metalation with [Ru-3(CO)(12)]. The porphyrin complex was immobilize ...

Increasing the melt viscosities of a polyester resin

Yves Leterrier

The invention relates to a process for increasing the melt viscosities of polyester resins. This process comprises a step of heating the polyester resin in the temperature range comprised between the melting temperature of the polyester resin and the degra ...

Star polymers: A study of the structural arrest in the presence of attractive interactions

Giuseppe Foffi

The structural arrest and the dynamics in star polymer solutions in the presence of attractive forces between microparticles were studied. The effect of the interplay between attractive interactions of different range and ultrasoft core repulsion, on the d ...

On the degradation and stabilization of poly(methyl methacrylate) in a continuous process

Thierry Meyer, Philip Nising

Thermally unstable polymers such as poly(Me methacrylate) are degraded considerably during industrial processing. This degrdn. and its redn. to a min. were investigated in both lab and continuous pilot-scale expts. A three-step degrdn. mechanism, starting ...

Polymer bonding by means of plasma activation

Hubert Girault, Joël Rossier

A low temperature method of bonding two polymer sheets (2, 3) without adhesive, at least one of said polymer sheets comprising a microstructure (1) or a network of microstructures, comprises the steps of treating at least a portion of one surface of one of ...

A ruthenium porphyrin catalyst immobilized in a highly cross-linked polymer

Kay Severin

[GRAPHICS] An immobilized Ru(meso-tetraarylporphyrin) complex was shown to be a very efficient catalyst for the epoxidation of olefins. In the presence of HBr, alcohols and even alkanes could be converted to the corresponding ketones. For the latter reacti ...

New Regeneration process of heavy metals loaded chelating resin

Albert Renken

An alternative to the classical acid-base regeneration of chelating resins loaded with heavy metals is investigated. The new process consists in recovering the heavy metals with recyclable soluble complexing agents. The semiclosed reactor includes a fixed ...
