    Abstract: The instant invention concerns the use of at least one polymer P obtained by radical copolymerization of a mixture of (i) acrylic acid; (ii) methacrylic acid; and (iii) at least one 2-hydroxyethyl methacrylate phosphate for treating a metallic surface intended to be coated by a paint, a varnish or an adhesive. The invention also concerns methods of coatings making use of this polymer P, compositions comprising the polymer P and useful for these methods, and the obtained coated materials.

    Abstract: The invention concerns the use as a fluxant agent of at least one compound with the formula (I) R1—X—R—Y—R2  (I) where: R1 and R2, which can be identical or different, are hydrocarbon chains, linear or branched, at C2-C11; each of —X— and —Y—, which can be identical or different, is an —O—(C═O)— group; —(C═O)—O—; —NR′—(C═O)—, where R′ represents a hydrocarbon atom or an alkyl radical at C1-C4, or —(C═O)—NR′—, where R′ represents a hydrocarbon atom or an alkyl radical at C1-C4, the —R— group is a divalent hydrocarbon chain, at C1-C10, linear or branched, and possibly interrupted by one or more oxygen atom(s) in a composition including a hydrocarbon binder for the preparation of the bituminous product based on solid mineral particles in contact with the said hydrocarbon binder, where the said compound of formula (I) is present in the said composition when the said composition is brought into contact with the said solid mineral particles.

    Abstract: Disclosed are soil additives capable of hydrophilizing soil particles and/or increase available water capacity in soil. The soil additive are capable of increasing the available water content/capacity (AWC) in soils, the additive in one embodiment comprising a polymer composition having a hydrophilic portion and a hydrophobic portion, wherein the hydrophobic portion of the copolymer binds with the soil particle surface and the hydrophilic portion of the copolymer can bind with water. This results in the prevention, arrest or decelerated loss of water from the targeted area, for example the plant root zone, which allows for improved water usage efficiency by plants, grasses, vegetation, etc.

    Abstract: The instant invention concerns polymers obtained by radical copolymerization of a mixture of (1) acrylic acid; (2) methacrylic acid; and (3) at least one allylcatechol selected from 4-allylbenzene-1,2-diol, 3-allylbenzene-1,2-diol and mixtures thereof. The polymers are especially useful for treating a metallic surface intended to be coated by a paint, a varnish or an adhesive. The invention also concerns methods of coatings making use of this polymer P, compositions comprising the polymer P and useful for these methods, and the obtained coated materials.
