ABSTRACT:
A composition and process for making an alternating copolymerization of acceptor monomers such as acrylic acid and derivatives thereof and donor monomers containing free amine groups therein such as an aminostyrene compound. The free amine groups are initially protected by conversion to an imide derivative such as phthalimide, or the like, and then reacted with the acceptor monomers. After copolymerization, the free amine is regenerated. The alternating copolymerization reaction is usually carried out in the presence of Lewis acids which act as complexing agents. The alternating copolymers of the present invention are useful as antistatic agents or as thickening agents as in oil recovery.
