Résumé :

Polyurethanes (PU) are widely used synthetic polymers. The growing amount of PU used industrially has resulted in a worldwide increase of plastic wastes. The related environmental pollution as well as the limited availability of the raw materials based on petrochemicals requires novel solutions for their efficient degradation and recycling. The degradation of the polyester PU Impranil DLN by the polyester hydrolases LC cutinase (LCC), TfCut2, Tcur1278 and Tcur0390 was analyzed using a turbidimetric assay. The highest hydrolysis rates were obtained with TfCut2 and Tcur0390. TfCut2 also showed a

Résumé :

During the course of these studies, polyester polyurethane foam has been found to be readily degraded in soil and marine environments. The incorporation of the formulation biocide Vinyzene E.P. reduced the rate and extent of degradation in test material exposed to soil conditions, but was found to be ineffective in preventing degradation when exposed to the marine environment. As a result of these studies, a number of fungi, representing a range of genera, have been isolated, identified, and shown using Kochian principles to degrade polyester polyurethane as a sole source of carbon.

Résumé :

As new family of composite materials, polyrotaxanes, polymers containing rotaxane units, have interested scientists world wide in last few decades because of their new properties. Crown ethers have been widely used as the cyclic component in various polyrotaxanes. However, due to significant loss of threaded cyclic during polymerization, the driving force for threading remains unidentified. To prevent threaded cyclics from slipping off the backbone during polycondensation, a diol blocking group (BG) and a diacid chloride BG were prepared and incorporated into polyesters as monomers or comono

Résumé :

Les polyHIPEs sont des matériaux cellulaires obtenus par polymérisation d’émulsions concentrées appelées HIPEs « High Internal Phase Emulsions ». La phase continue de l’émulsion contenant les monomères est le siège de la polymérisation permettant la création de la matrice solide. La phase dispersée engendre la porosité. Les matériaux polyHIPEs sont généralement synthétisés par polymérisation radicalaire. La variété des monomères utilisables est donc ainsi limitée. La majorité des polymères à haute performances étant obtenus par polycondensation, il serait d’un grand intérêt d’élargir la gamme

An A2 + B3 polymerization for the synthesis of hyperbranched polymers was altered using oligomeric precursors in place of either one or both of the monomer pairs to synthesize highly branched macromolecules. Unique topologies that are intermediates between long-chain branched and hyperbranched structures were obtained and the term "highly branched" was used to define these novel architectures. Various types of highly branched polymers, such as polyurethanes, poly(urethane urea)s, poly(ether ester)s, and poly(arylene ether)s were synthesized using the oligomeric A2 + B3 strategy.
