Title
(EN) CEMENT MODIFIER COMPOSITIONS
(FR) COMPOSITIONS DE MODIFICATEUR DE CIMENT
Abstract
(EN)
Described herein are emulsion polymers, spray dried powders made with said emulsion polymers, and cementitious compositions made with said emulsion polymers or said spray dried powders. Emulsion polymers described herein comprise a shell portion comprising an alkali soluble resin (ASR), a core portion formed from polymerized units of at least one hydrophobic ethyienically unsaturated monomer, wherein no crosslinker is present when the shell portion and core portion are combined, and a nonionic water-soluble polymer.
(FR)
L'invention concerne des polymères en émulsion, des poudres séchées par pulvérisation fabriquées avec lesdits polymères en émulsion, et des compositions cimentaires fabriquées avec lesdits polymères en émulsion ou lesdites poudres séchées par pulvérisation. Les polymères en émulsion décrits ici comprennent une partie enveloppe comprenant une résine soluble dans les alcalis (ASR), une partie cœur formée à partir d'unités polymérisées d'au moins un monomère hydrophobe éthyléniquement insaturé, aucun agent de réticulation n'étant présent lorsque la partie enveloppe et la partie cœur sont combinées, et un polymère non ionique soluble dans l'eau.
