This class of compounds provides a high dense foam and unique solubility in many organic solvents as well as very substantive salts of the carboxylic acid when neutralized with base. The compounds of the present invention are prepared by reacting a the hydroxyl group in a silicone polymer with an anhydride, followed by neutralization with an amine.Field of SearchThe carbonyl is part of a -COO- groupOrganic Si-free reactant is a carboxylic acid or derivative Organic Si-free reactant contains a heterocyclic ring Organic Si-free reactant is a nitrogen-containing compound Boron, silicon, selenium, or tellurium containing Boron, selenium, or silicon containing Boron or silicon containing |
