Abstract

L'invention se rapporte aux matériaux polymères. Elle concerne un procédé de polymerisation en émulsion pour la préparation de polymères de méthacrylate de méthyle et de copolymères contenant au moins 60 % en poids de méthacrylate de méthyle selon lequel a on ajoute par portions successives en deux étapes ou plus, dans de l'eau, au moins un monomère qui est du méthacrylate de méthyle en même temps qu'un initiateur de polymérisation et un agent de transfert de chaîne de manière qu'au moins la majeure partie du monomère ajouté dans une étape donnée soit consommée avant l'addition de la portion suivante, et b on isole le polymère résultant. Ce procédé est caractérisé en ce que l'étape a est effectuée en l'absence de tout émulsionnant ou agent tensio-actif, et l'étape b est conduite à une température inférieure d'au moins 30 degrés C à la température de transition vitreuse du polymère. Le produit obtenu est utile pour la préparation de plastisols et d'organosols.The invention relates to polymeric materials. It relates to an emulsion polymerization process for the preparation of polymers of methyl methacrylate and of copolymers containing at least 60% by weight of methyl methacrylate according to which a successive portions are added in two or more stages in water , at least one monomer which is methyl methacrylate together with a polymerization initiator and a chain transfer agent so that at least the major part of the monomer added in a given step is consumed before the addition of the next portion, and b isolating the resulting polymer. This process is characterized in that step a is carried out in the absence of any emulsifier or surfactant, and step b is carried out at a temperature at least 30 degrees C below the glass transition temperature. polymer. The product obtained is useful for the preparation of plastisols and organosols.
