Tests de toxicitéIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Waterborne reactive polymers that contain pendant 2-oxazoline groups were prepared by radical copolymerization of 2-alkenyl-2-oxazoline and unsaturated co-monomers. By varying the composition of co-monomers, a series of emulsion polymers with the various glass transition temperatures (Tg) or water-soluble polymers with high oxazoline contents were prepared. The crosslinking reactions of these oxazolidine-functional polymers with waterborne carboxylated polymers were examined.
As a result, the oxazoline-functional polymers show sufficient reactivity and stability to be used as a low-toxic, one-packed crosslinker providing improved properties for waterborne carboxylated polymer. The pH value of the formulation has an important effect on its reaction rate and pot life. It was also found that the mechanical property of cured film can be controlled by selecting the composition of backbone polymer in the oxazoline-functional polymer. Furthermore, the performances of waterborne acrylic adhesives using these oxazoline-functional polymers as the crosslinker were discussed.Note de contenu : - RESULTS & DISCUSSION : Preparation of oxazoline-functional polymers - Reaction of oxazoline-functional polymer with carboxylated acrylic-styrene copolymer emulsion

PolyadditionIndex. décimale : 667.2 Colorants et pigments Résumé : The appropriate substituents have been added to a 7H-benzimidazo[2,1-a]benz[de]isoquinolin-7-one skeleton in order to obtain a one-component initiator system. The absorption, fluorescence, and electrochemical properties of these naphthoylenebenzimidazolone dyes and their usefulness as visible light initiators of free radical polymerisation of trimethylolpropane triacrylate were examined. The initiation efficiency of these dyes was compared with that of the parent 7H-benzimidazo[2,1-a]benz[de]isoquinolin-7-one in the presence of a coinitiator. Results show that these bifunctional dyes are able to initiate polymerisation without an additional coinitiator. Photopolymerisation studies and the relationship between the rate of polymerisation and the free energy change for electron transfer revealed that, depending on the concentration, initiating radicals are generated via intra- and intermolecular electron transfer.

Revêtements protecteursIndex. décimale : 667.9 Revêtements et enduits Résumé : Recent advances in photoinitiated cross-linking will be presented, in particular regarding the efficiency of novel photoinitiators, monomers and functionalised oligomers, as well as the performance of the polymers obtained by this environmental-friendly technology. Such ultra-fast reactions can be easily followed in real-time and quantitatively by infrared spectroscopy, to assess the influence of chemical and physical parameters on the polymerisation kinetics. Because of their remarkable properties and high resistance, such ultraviolet (UV)-cured coatings proved particularly efficient to protect a large variety of materials (plastics, metals, paper, wood) against chemical attack, corrosion and weathering.

Revêtements -- Effets du rayonnement ultravioletIndex. décimale : 667.9 Revêtements et enduits Résumé : A novel photoinitiating system uses a copper photoredox catalyst (G1) in combination with an iodonium salt and N-vinylcarbazole.
