Title (EN) AQUEOUS AUTOXIDISABLE POLYMER DISPERSIONS
(FR) DISPERSIONS AQUEUSES DE POLYMERES AUTO-OXYDABLES
Abstract:
(EN) Aqueous autoxidisable dispersions of film-forming polymer. A water-bone autoxidisable film-forming material free from many of the deficiencies of previous materials comprises an aqueous dispersion of particles of film-forming polymer, the particles comprising a mixture of an addition polymer and a chemical compound comprising at least two groups of the formula CH2 = CR-CH2-O- where R is H or CH3. The chemical compound may be polymeric or non-polymeric, and the particles may additionally comprise other polymer. A preferred method of preparation is the mixing of ethylenically unsaturated monomer, chemical compound, stabilising compound and water to give a stable aqueous dispersion of monomer-chemical compound particles, followed by the polymerisation of the monomer. When the stabiliser is an amphipathic compound, it must be free of ethylenic unsaturation. The dispersions of this invention are useful in the preparation of air-drying coating compositions and adhesives.
(FR) Dispersions aqueuses auto-oxydables d"un polymère formant une pellicule. Un matériau à support aqueux auto-oxydable et formant une pellicule, exempt de la plupart des défauts des matériaux antérieurs, comprend une dispersion aqueuse de particules d"un polymère formant une pellicule, les particules comprenant un mélange d"un polymère d"addition et d"un composé chimique comprenant au moins deux groupes de formule CH2 = CR-CH2-O-, où R est H ou CH3. Le composé chimique peut être polymère ou non polymère, et les particules peuvent également comprendre d"autres polymères. Un procédé préférentiel de préparation consiste à mélanger un monomère éthyléniquement insaturé, un composé chimique, un composé stabilisateur et de l"eau pour obtenir une dispersion aqueuse stable de particules de monomère-composé chimique, après quoi on provoque la polymérisation du monomère. Lorsque le composé stabilisateur est un composé amphipathique, il doit être exempt d"insaturation éthylénique. Les dispersions décrites par la présente invention sont utiles dans la préparation de compositions de revêtements et d"adhésifs séchant à l"air.
