ABSTRACT:
Functionalized terpolymers of two different .alpha.-olefin and para-alkylstyrene are disclosed, wherein the functionalized terpolymers have a substantially homogeneous compositional distribution represented by the formula: ##STR1## in which R.sub.1, R.sub.2, R' and R" independently, are hydrogen or a primary or secondary alkyl group; X is a functional group, such as --COOH, --OH, --SH, --NH.sub.2, --Cl, --Br, --M, --COOM (M =metals, e.g. Li, Na, K and Ca) and anhydrides; P is a polymer having a molecular weight of at least 500; Y is chemical linkage between polymer P and para-alkystyrene side chain; and the combination of a+b+c+d+e represents the empirical formula of a substantially random functional polymer; where both a and b are greater than 0; where the sum of a+b ranges from about 50 to 100,000; where each of c, d and e range from 0 to 10,000; where both d and e can not be 0; and where the sum of c+d+e is at least 1.
