  • Publication number: 20070265428
    Abstract: A novel monomer composition and a process of synthesizing the novel monomer is described. Generally, such novel monomers have an aliphatic spacer unit between two phenyl rings. In one embodiment the inventive monomer has a general structure of: wherein X and X? independently include a functional group selected from the group consisting of hydroxy, halogen, nitro, carboxylic acid, trimethylsiloxy and amines; G and G? independently include one selected from the group consisting of hydrogen, sulfonic acid, phosphoric acid, carboxylic acid, sulfonamide, and imidazole; “m” and “o” being integers and each independently having a value in the range from 0 to 15. The aliphatic spacer unit in alternative described embodiments of the inventive monomer does not contain the fluorinated methylene unit. Novel processes of synthesizing such monomers are also described. Based on these inventive monomer compositions, inventive polymer structures and processes of synthesizing them are also described.

  • Publication number: 20060089510
    Abstract: A novel monomer composition is described. The novel monomer composition includes at least one property imparting unit. The property imparting unit has at least one member selected from the group consisting of conductivity imparting unit, stability imparting unit and any combinations thereof. The novel monomer may further include a delinking agent, which is attached to at least one of said property imparting unit. The delinking agent includes at least one member selected from the group consisting of C—C bond, CH2, CH3, CF2, CF3, Si, O, S, functional groups, aromatic residues and any combinations thereof.
