摘要： The invention relates to environmentally friendly flame retardant nucleating compositions, and corresponding formulations and processes useful for the production of polystyrene foams with low densities and a very low halogen content in the final product. The flame retardant composition according to the present invention achieves good flame retardancy and excellent recycling performances, with about the same loading of traditional halogenated compound, which does not affect the process and the physical and mechanical properties of the final foam and can be considered halogen free, according to some international standards.

摘要： A method is disclosed to inhibit scale formation in aqueous systems whereby a threshold amount of a scale inhibiting agent, represented by an aminoacid alkylphosphonic acid, is added to the aqueous system. The aminoacid moiety can be represented by α-species or by species having, at least, two or more carbon atoms between the carboxylic moiety and the amine group. These aminoacid based inhibitors exhibit unusually superior performance and system acceptability compared to leading state-of-the-art inhibitors.
