Abstract: Bifunctional primer naphthalene compounds having the formula: wherein M″ is an alkali metal, preferably sodium or lithium, and R1 and R2 are, e.g., alkyl radicals, are prepared from corresponding 1,5-diethenylnaphthalene derivatives, and are well suited for the improved anionic polymerization of diene, vinylaromatic and/or (meth)acrylic monomers.

Abstract: The method includes the steps of: preparing an organic mixture of oil, monomers selected among acrylic acid—and methacrylic acid esters and at most 25% of an acrylic or methacrylic monomer having an acide, amide, amine or epoxy group; placing the mixture in mini-emulsion in an aqueous phase in the presence of a co-solvent, preferably of the polyalkylene glycol type; and copolymerising the monomers in emulsion. When the emulsion is applied in a thin coating on a metal surface, it provides simultaneously a dry appearance, efficient protection and a pre-lubricating effect.
