ABSTRACT Addition interpolymers with pendant ionic moieties and pendant reactable silane moieties are prepared by addition polymerization of ethylenically unsaturated monomers having ionic moieties with organofunctional silane compounds having ethylenic unsaturation in the organofunctional moiety of the silane where the silane also has reactable alkoxy and/or hydroxy groups. The addition polymerization is performed in the presence of a free radical initiator at an elevated temperature up to around 90°C and in an nonoxidizing atmosphere. The amount of the ionic monomer is effective to result in the interpolymer having at least water dispersibility and most suitably water emulsifiability and the amount of the silane monomer is in the range of about 1 to about 15 weight percent of the interpolymer. The interpolymer may be prepared with one or more additional ethylenically unsaturated monomers where the amount does not decrease the ionic character of the interpolymer below that which renders the interpolymer water emulsifiable.
