Abstract: The present invention relates to grafted ethylene polymers and copolymers characterized in that they are thermoplastic and, if appropriate, crosslinkable and soluble at ambient temperature in organic solvents and/or aqueous media and in that they are prepared by polymerization of (in % by weight relative to the resin obtained):0.5 to 30% of at least one unoxidized polyethylene and/or an unoxidized ethylene copolymer based on at least 70% by weight of ethylene, the said polyethylene or ethylene copolymer being defined by the following properties:a weight average molecular weight (Mw) between 900 and 60,000,a Brookfield viscosity at 190.degree. C. of between 0.1 and 500 poises and/or a Brookfield viscosity at 140.degree. C. of between 0.1 and 2,000 poises.a crystallinity, measured using X rays, of between 10% and 80%,and, if desired, containing ester, anhydride or acid functional groups originating from the ethylene comonomers,70 to 99.

Abstract: Copolymers produced from 0.5-20% by weight mono-, bis- or trismethylolphenyl allyl ether (I) of formula: ##STR1## n being from 1 to 3, and from 80-99.5 % by weight ethylenic monomers, at least one being a (meth)acrylic monomer are useful in the preparation of coatings, particularly in the field of paints, varnishes, inks and adhesives. Radical polymerization is employed with different stages of polymerization.

Abstract: New resins based on oxidized polyethylene, which are thermoplastic or thermosetting, soluble in solvents and/or aqueous media, are characterized in that they consist essentially of grafted polyethylene obtained by preparing a dispersion of a molten oxidized polyethylene in an organic solvent medium at a temperature above the softening range of the oxidized polyethylene. The oxidized polyethylene is employed in a proportion of 0.5 to 30% by weight of the resin and has a weight average molecular weight of between 900 and 25,000 and also contains side groups ending in functional groups capable of giving rise to free radicals. The dispersion is polymerized with a mixture of catalyzed monomers consisting essentially of acrylic and/or methacrylic monomers, in a proportion of 70 to 99.5% by weight based on the resin, the mixture being added gradually during the reaction.The resins according to the invention can be employed as a binder for coatings in paints, varnishes, glues, inks, adhesives and sealants.
