Abstract: A halogenated benzoxazine compound, which can be used in particular as monomer in the synthesis of polybenzoxazine, corresponds to the formula: in which: each benzene nucleus of the two oxazine rings bears at least one halogen (represented by the symbol Hal), in particular bromine, chlorine or fluorine; and Z1 and Z2, which are identical or different, represent an aliphatic, at least divalent, bonding group comprising at least one carbon atom and optionally at least one heteroatom chosen from O, S, N and P.

Abstract: The repeat units of a polybenzoxazine comprise at least one unit corresponding to the formulae (I) or (II): in which Z1 represents an at least divalent, aliphatic, cycloaliphatic or aromatic bonding group comprising at least one carbon atom and optionally at least one heteroatom selected from O, S, N and P; X1 and X2, which are identical or different, represent O or S; Ar1 and Ar2, which are identical or different, represent a substituted or unsubstituted phenylene group; and Z2 represents O or (S)n, the symbol “n” representing an integer equal to 1 or greater than 1. Such a polybenzoxazine can be used as metal-adhesive layer, in particular for the adhesive bonding of a metal substrate, in particular made of carbon steel, to a rubber.

Abstract: A polymer has urethane or thiourethane units, which can be used, in particular, as an adhesion primer for the adhesive bonding of metal or glass to rubber. The polymer comprises base units comprising at least a sub-unit of formula X1CO—NH—, in which X1 respectively represents O or S, and additional units comprising at least a secondary alcohol function and a thioether function in the ? position relative to the alcohol function. The polymer can be used as an adhesion primer for the adhesive bonding of a substrate, for example glass or metal, to an unsaturated rubber, or as a corrosion-resistant protective coating for a metal substrate. A metal reinforcer, such as wire, cord, film or plate, can be coated with the polymer.

Abstract: A polyurea comprises at least urea base units of formula —NH—CO—NH— and additional units. The additional units comprise at least, on the one hand, a secondary alcohol functional group and, on the other hand, an ether, thioether or secondary amine functional group in the alpha position with respect to the secondary alcohol functional group. Such a polymer can be used as an adhesion primer for the adhesive bonding of a substrate, for example, glass or metal, to an unsaturated rubber or as corrosion-resistant protective coating for a metal substrate. Metal reinforcers, such as thread, cord, film or plate, coated can also be coated with such a polymer.

Abstract: A method of modifying a particle that includes reacting a reactive compound having an X—[Y]n reactive group with a secondary compound N—S-ZM to form a substituted reactive intermediate [Y]a—X—(N—S-ZM)b, and reacting the particle with the substituted reactive intermediate [Y]a—X—(N—S-ZM)b to attach the substituted reactive intermediate to the surface of the particle to form a surface modified particle. The particle may comprise at least one of a dye particle, an inorganic pigment particle, an additive, or a combination thereof. X may be a sulfonyl, phosphoryl, or 1,3,5-triazinyl group. Y may be a halogen leaving group. N may be a nucleophilic group. S may be an organic group. ZM may be an ionizable end group. Also, n is an integer between 1 and 3, b is an integer between 1 and 3, and a=n?b. When n is equal to or greater than b, and wherein if b is 2 or 3, each N—S-ZM can be the same or different.
