Abstract
The present invention relates to methods and polymers based upon vinyl type monomers that contain pendant carboxylic acid groups and ester group functionality. The polymerization methods include regulation of heat flow such that parameters of monomer conversion, acid functionality, molecular weight, tacticity and/or copolymer composition may be adjusted to selected levels for a selected application.
