  • Continuous process and system for producing polymers comprising maleic anhydride and certain alpha-olefins
    Patent number: 4849489
    Abstract: A continuous process and system for producing a polymer comprising maleic anhydride and alpha-olefin monomeric units is disclosed. The process comprises combining monomeric reactants comprising the maleic anhydride and the alpha-olefin, in the presence of a minimal effective amount of a solvent, to produce a polymerizable reaction mixture. The solvent is present in minimal amounts, namely, at about 2 to about 9 weight percent, based upon the weight of the reaction mixture. The polymerizable reaction mixture is heated; and at least one thermally-decomposable initiator is added to the thus-heated, polymerizable reaction mixture to initiate the polymerization reaction. The presence of the initiator causes the maleic anhydride and the alpha-olefin to polymerize, thereby producing the desired polymer.
