Estimating the term…
An oligomer, uncured polymer or cured polymer comprising the reaction product of one or more polyfunctional compounds containing two or more cyclopentadienone groups and at least one polyfunctional compound containing two or more aromatic acetylene groups wherein at least some of the polyfunctional compounds contain three or more reactive groups. Such oligomers and uncured polymers may be cured to form cured polymers which are useful as dielectrics in the microelectronics industry, especially for dielectrics in integrated circuits.
An oligomer, uncured polymer or cured polymer comprising the reaction product of one or more polyfunctional compounds containing two or more cyclopentadienone groups and at least one polyfunctional compound containing two or more aromatic acetylene groups wherein at least one of the polyfunctional compounds contain three or more groups selected from the group consisting of acetylene groups and cyclopentadienone groups.
An oligomer or uncured polymer having the formula:
A polyfunctional compound of the general formula:
Oligomers, uncured polymers or cured polymers comprising the reaction product of at least one aromatic monomer containing at least one cyclopentadienone moiety and at least one acetylene moiety.
A polyfunctional compound of the general formula:
4-(4-(Phenylethynyl)phenyl)-2,3,5-triphenylcyclopentadienone.
3,4-Bis(.sup.4 -(phenylethynyl)phenyl)-2,5-diphenylcyclopentadienone or 3,4-Bis-(3-(phenylethynyl)phenyl)-2,5-diphenylcyclopentadienone.
3,3'-(1,4-Phenylene)bis(2,5-di-(4-fluorophenyl)-4-phenylcyclo pentadienone).
2,4-Cyclopentadien-1-one, 3-(4-ethynylphenyl)-2,4,5-triphenyl.
