The sulfur and electron withdrawing group containing ligand portion(s) of the compound has an affinity for the desired ions to form a complex thereby removing the desired ions from the source solution. The desired ions are removed from the compound by contacting the compound with a much smaller volume of a receiving solution having a greater affinity for the desired ions than does the sulfur and electron withdrawing group containing ligand portion of the compound.

  • Patent number: 5149839
    Abstract: Silane coupling agents and a method of preparing the coupling agents are provided in which a silane coupling agent is prepared by reacting 2.3 to 4.0 mols of a haloalkylalkoxysilane with 1 mol of a diamine having N atoms to which 4 active hydrogen atoms are bound, by reacting 1.3 to 3.0 mols of a haloalkylalkoxysilane with 1 mol of a diamine having N atoms to which 3 active hydrogen atoms are bound and to which one alkylsilyl group is bound, or by reacting 0.3 to 2.0 mols of a haloalkylalkoxysilane with 1 mol of a diamine having N atoms to which 2 active hydrogen atoms are bound and to which 2 alkylsilyl groups are bound. In addition, a silane coupling agent may be prepared by reacting the diamine with a haloalkylalkoxysilane and a halomethylstyrene.

  • Patent number: 5145937
    Abstract: New polyimides have been prepared from the reaction of aromatic dianhydrides with novel aromatic diamines containing carbonyl and ether connecting groups between the aromatic rings. Several of these polyimides were shown to be semi-crystalline as evidenced by wide angle x-ray diffraction and differential scanning calorimetry. Most of the polyimides form tough solvent resistant films with high tensile properties. Several of these materials can be thermally processed to form solvent and base resistant moldings.
