Abstract
A novel reaction product and method for making the reaction product. The reaction product is a copolymer obtained by reacting together i) an acylated alkylacrylate copolymer having a number average molecular weight ranging from about 5,000 to about 500,000; ii) a hydrocarbyl acylating agent having a number average molecular weight ranging from about 500 to about 5000; and iii) a compound selected from the group consisting of (a) a polyamine; (b) a polyol; and (c) an aminoalcohol to provide a functionalized polyalkylacrylate copolymer. According to the reaction, a mole ratio of component (i) to (ii) ranges from about 1:10 to about 5:1.
