  • Graft copolymers having anhydride functionality
    Patent number: 5633091
    Abstract: An anhydride-functional polymer obtained by reacting under graft copolymerization reaction conditions,(A) an unsaturated polymer which was obtained by reacting under ene reaction conditions a mixture of reactants comprising:(i) an unsaturated anhydride having the structure: ##STR1## wherein R.sub.1 and R.sub.2 are each independently hydrogen, alkyl of 1 to about 6 carbons, or alkoxy of 1 to about 6 carbons, or a halogen; and(ii) at least one polyolefin having at least two carbon-carbon double bonds in the polyolefin backbone and having an average of at least three carbon atoms in the polyolefin backbone between the carbon-carbon double bonds; and(B) at least one ethylenically unsaturated monomer which is copolymerizable with the unsaturated polymer.
    Type: Grant
