摘要： A flame retardant polymer composition is described. The composition can include at least one polymer and a hypophosphite salt, wherein the hypophosphite salt is heat stabilized so that when it is heated for 3 hours at 298° C. under a flow of argon flushing at rate 58 mL/min, it generates less than 0.5 mL of phosphine per gram of hypophosphite salt. The polymer can be an epoxy resin, a phenolic resin, an acrylonitrile-butadiene-styrene resin, a styrene-acrylonitrile resin, a mixture of high impact polystyrene and polyphenylene oxides, a styrene-butadiene rubber, a polylactic acid or a polyvinyl chloride.

摘要： An additive for a bitumen or polymer modified bitumen product, which is prepared by mixing together a sulphur-based product, a vulcanized rubber, for example, a waste vulcanized rubber, preferably a fatty acid, and a bitumen, is described. The use of this additive for preparing, with very limited gaseous emissions, elastomer-containing bituminous product is also described. Such use may be especially suitable for making bituminous coated material including, for example, asphalt concrete.

摘要： A process for preparing a 5-halophenol, ortho-substituted by an electron-donating group, is described. Also described, is a process for preparing a sulphonic ester of an ortho-substituted phenol, which is the synthesis intermediate for the ortho-substituted 5-halophenol. The process for preparing a phenol ortho-substituted by an electron-donating group and protected in the form of a sulphonic ester can include reacting a phenol ortho-substituted by an electron-donating group with a sulphonylating agent in the presence of a Lewis acid. The process for preparing a 5-halophenol ortho-substituted by an electron-donating group can include a first step of preparing a phenol ortho-substituted by an electron-donating group and protected in the form of a sulphonic ester, as described above; a second step of halogenating the protected phenol intermediate obtained in the preceding step, in the position para to the electron-donating group; and a third step of deprotecting the sulphonic ester function to hydroxyl.
