Abstract
In one embodiment, the present invention provides a method of making a polymer-organoclay composite composition comprising (a) contacting under condensation polymerization conditions a first monomer, a second monomer, a solvent, and an organoclay composition, said organoclay composition comprising alternating inorganic silicate layers and organic layers, to provide a first polymerization reaction mixture, wherein one of said first monomer and second monomers is a diamine and the other is an dianhydride; (b) carrying out a stoichiometry verification step on the first polymerization reaction mixture; (c) optionally adding additional reactant (monomer 1, monomer 2, or chainstopper) to the first polymerization reaction mixture to provide a second polymerization reaction mixture; and (d) removing solvent from the first polymerization reaction mixture or the second polymerization reaction mixture to provide a first polymer-organoclay composite composition comprising a polymer component and an organoclay component wherein the organoclay component is at least 10% exfoliated.
