摘要:
The process of producing a stable polymer dispersion by aqueous emulsion polymerization of an ethylenically unsaturated monomer in the presence of a stabilizer selected from a polyester or polyamide containing a sulfate or sulfonate group.
摘要:
The invention relates to polymers of formula (I) ##STR1## in which R.sup.1 and R.sup.2 represent optionally substituted alkylene, cycloalkylene or phenylene radicals, A represents hydrogen or carboxyl groups, B represents hydrogen or groups derived from carboxylic acids or isocyanates. The invention also relates to aqueous epoxy resin dispersions containing one or more polymers of general formula (I) in addition to bases, acid, one or more emulsifiers and, optionally, other active substances and auxiliaries typically used in epoxy resin dispersions and also water.The invention also relates to a process for the production of such aqueous epoxy resin dispersions and to the use of such resins in processes for the autophoretic coating of metallic surfaces.
