Abstract: The invention relates to a process for the preparation of alkylimidazolidone (meth)acrylates, generally expressed as compound (I): that are prepared by reacting at least one (meth)acrylate of formula (II): with a heterocyclic alcohol of formula (III): in the presence of a catalyst comprising at least one compound (a) which is a chelate formed of lithium and of a 1,3-dicarbonyl compound. The invention also relates to a composition comprising compound (I) in solution in (meth)acrylate (II). Finally, the invention involves the use of the abovementioned composition in the preparation of polymers that can be used as coatings and adhesives, in the treatment of paper and of textiles, as agent for leather treatment and in the production of paints with high wet adhesion characteristics.

Abstract: A system for transferring a fluid product between a carrier, such as a vessel, and an installation, in particular a fixed installation, for processing and storing the product. The system includes a tubular structure for conveying the product between the vessel and the installation, a device for connection to a manifold of the vessel and a flexible transfer pipe connected to the installation. The connection device and the pipe are connectable to each other at free ends for transferring the fluid product between the vessel and the installation. At least the free end of the flexible transfer pipe includes a product handler for displacing the free end between a position for connection to the connection device and a disengaged position for storage. The invention enables the transfer of cryogenic liquefied natural gas.

Abstract: The invention relates to a process for the preparation of alkylimidazolidone (meth)acrylates, generally expressed as compound (I): 1

Abstract: The invention relates to a process for the batchwise preparation of (meth)acrylic anhydride, in which acetic anhydride is reacted with (meth)acrylic acid and the acetic acid is at least partly removed gradually as it is formed.

Abstract: The present invention relates to a plastic blend of polymers, capable of being injected and extruded, the process for producing it and its applications.This blend is produced by extrusion of a matrix of heat-stable material consisting of a polysulfone resin or polyphenylene sulfide and of a filler of a fluorocarbon polymer resin, the extrusion producing a network of interconnected and inter-penetrated fibers of filler within the matrix.This blend can be employed in an aggressive environment and at a high temperature, particularly for the manufacture of components of electrochemical reactors such as electrolysis cells.
