ABSTRACT:
Functionalized copolymers of .alpha.-olefin and para-alkylstyrene having the formula: ##STR1## in which in which R, R' and R", independently, are hydrogen or primary or secondary alkyl groups; X comprises 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 comprises a polymer having the molecular weight of at least about 500, which can be derived from both step and chain polymerization reactions; Y is a chemical linkage between polymer P and para-alkystyrene side chain, which is also a residue derived from graft reaction; and the combination of a+b+c+d represents the empirical formula of a substantially random functional polymer, where a ranges from about 50 to about 100,000, b, c and d range from 0 to about 10,000, and the sum of c+d is at least 1, and processes for preparing the funcitonalized copolymers are disclosed.
