ABSTRACT:
This invention describes hydroxyamino-derivatized polymers of .alpha.-olefin-maleic anhydride in the form of their maleimide, maleamic acid and .alpha.-olefin-maleic anhydride half-acid/half ester or full acid repeat units process for making same. The polymers are made by reacting an .alpha.-olefin-maleic anhydride, half-acid/half-ester or full acid with a hydroxy containing .alpha.-unsubstituted primary amine in aqueous or aqueous alcoholic solution at a temperature of about 60.degree.-160.degree. C. during a reaction period of about 1-25 hours.
