Title
(EN) CATIONOMERIC POLYOLEFIN COMPOSITIONS AND METHODS FOR PRODUCTION AND USE THEREOF
(FR) COMPOSITIONS DE POLYOLÉFINE CATIONOMÉRIQUE ET LEURS PROCÉDÉS DE PRODUCTION ET D'UTILISATION
Abstract
(EN)
Although polyolefin elastomers are widely employed commodity polymers, there are shortcomings of this class of polymers for certain applications. For example, the rheological properties of some polyolefin elastomers may be insufficient to provide the green strength or low shear viscosity necessary to form stable foams, or to provide sufficient viscosity modification effects when present in a solvent. Cationomeric modification of polyolefin elastomers may alleviate these difficulties. Such polyolefin elastomers may feature a random cationomeric polyolefin copolymer comprising at least a first monomer and a second monomer, in which the first monomer is a neutral monomer and the second monomer has a side chain bearing a cationic moiety. The polyolefin elastomers may be present in foamed polyolefin compositions comprising a gas component and/or in liquid compositions comprising a solvent in which the polyolefin elastomer is dissolved.

Bien que les élastomères de polyoléfine soient des polymères de produits largement utilisés, il existe des inconvénients pour ce type de polymères pour certaines applications. Par exemple, les propriétés rhéologiques de certains élastomères de polyoléfine peuvent être insuffisantes pour fournir la résistance initiale ou la faible viscosité de cisaillement nécessaire pour former des mousses stables, ou pour fournir des effets de modification de viscosité suffisants lorsqu'ils sont présents dans un solvant. La modification cationomérique d'élastomères de polyoléfine peut atténuer ces difficultés. Lesdits élastomères de polyoléfine peuvent comprendre un copolymère de polyoléfine cationomérique aléatoire comprenant au moins un premier monomère et un second monomère, le premier monomère étant un monomère neutre et le second monomère ayant un segment latéral portant une fraction cationique. Les élastomères de polyoléfine peuvent être présents dans des compositions de polyoléfine expansée comprenant un composant gazeux et/ou dans des compositions liquides comprenant un solvant dans lequel l'élastomère de polyoléfine est dissous.
