摘要

Disclosed is a metal containing polymer composition comprising: a metal overbased imide or ester functionalized polymer prepared by reacting (A) a polymer comprising (A1) an acidic functionalized polymer or ester functionalized polymer; (A2) an acidic mixed esteracid of a carboxy containing interpolymer; or (A3) an ester functionalized polymer comprising a lactone and (B) a metal overbased composition that contains a reactive basic functionality comprising (B1) a metal overbased amine wherein the reactive basic functionality is a primary or secondary amino group; (B2) a metal overbased hydroxy substituted carboxylic acid wherein the reactive basic functionality is a hydroxy group; or (B3) a metal overbased dispersant wherein the reactive basic functionality is a primary or secondary amino group.
