  • NANOPOROUS LAMINATES
    Publication number: 20040247880
    Abstract: A process of making a nanoporous substrate, such as the matrix in an electrical laminate, by grafting onto an organic resin backbone a thermolabile functionality by reacting hydrogen active groups of the organic resin with a compound containing thermolabile groups; then thermally degrading the thermolabile groups grafted on the organic resin to form a nanoporous laminate. Advantageously, the nanoporous electrical laminate has a low dielectric constant (Dk) because of the nanopores present in the laminate matrix.

  • Thermosetting polyimide schiff base resins, their preparation and their applications
    Patent number: 5064934
    Abstract: Thermosetting Schiff base resins, their preparation and their applications re described.These thermosetting Schiff base resins can be defined as responding to the general formula: ##STR1## Radicals Ar.sub.1, Ar.sub.2 and Ar.sub.3 are chosen so that the softening temperature of the resins is less than about 150.degree. C.The resins can be prepared by direct condensation of an ethynyl benzaldehyde or acetophenone on a telechelic diamine oligomer obtained by reaction of a diamine containing flexibilizing groups on a derivative of benzhydrol tetracarboxylic acid. These Schiff base resins can be used by bulk thermal polymerization particularly to prepare adhesives or composite matrices.
