Patent number: 7910677Abstract: 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. The polymers may then be used in detergent formulations.Type: GrantFiled: September 30, 2009Date of Patent: March 22, 2011Assignee: University of New HampshireInventors: Yvon Durant, Ming Cao, Mathieu Chirat
