The present invention relates to methods and polymers based upon vinyl type monomers that contain pendant carboxylic acid groups and ester group functionality. The polymers may be prepared under selected conditions of partial neutralization to provide relatively high conversions and/or relatively high values of molecular weight and/or selected amounts of repeating unit tacticity.
La présente invention concerne des procédés et des polymères à base de monomères de type vinylique qui contiennent des groupes acides carboxyliques pendants et une fonctionnalité ester. Les polymères peuvent être préparés dans des conditions choisies de neutralisation partielle pour fournir des taux de conversion relativement élevés et/ou des valeurs de masse moléculaire relativement élevées et/ou des quantités choisies de tacticité d'unités récurrentes.
