<p>A macromonomer composition, wherein at least 80 mol % of the macromonomer is a random copolymer of 2 to 1,000 units of monomers and having a very high content of acid monomers, i.e. >50% by weight of acid monomers, and an end group linked to the random copolymer having the formula: CH2=C(C(O)OR1)(CH2 &rparstr& , wherein R1 is selected from the group consisting essentially of H; an alkyl group of 1 to 8 carbon atoms; and Xn(CH2CH2O)m-R4 wherein n is 0 or 1, X is an alkyl, aryl or alkaryl diradical connecting group of 1 to 9 carbon atoms, m is 2 to 50, and R4 is H or an alkyl group of 1 to 4 carbon atoms. These macromonomers can be used effectively in solution form to prepare structured polymers such as block copolymers and graft copolymers for industrial applications.</p> |
