Abstract
Compositions for providing a dielectric layer in an electronic device wherein the composition comprises a polymer which polymer contains one or more building blocks, wherein at least 25 mol % of the total number of building blocks in the polymer are of the general formula having olefinic oligo-dihydrodicyclopentadienyl functionalities.
Claims14
A composition for providing a dielectric layer in an electronic device, the composition comprising:
- a polymer containing one or more units, wherein at least 25 mol % of the total number of units in the polymer are the following units (A) with crosslinkable side groups,
- in which
- X independently at each occurrence is a methylene group or oxygen,
- R independently at each occurrence is a methyl group or hydrogen,
- L1 is a divalent group which connects the polymer chain to the side group, and
- L2 is a divalent group which connects the polymer chain to the side group.

- R independently at each occurrence is a methyl group or hydrogen,
- L1 is a divalent group which connects the polymer chain to the side group and
- L2 is a divalent group which connects the polymer chain to the side group.
An electronic device comprising a thin-film capacitor including at least one dielectric layer, wherein the at least one dielectric layer comprises:
- a) a crosslinked polymer obtained by polymerizing monomers to obtain a polymer including at least 25 mol % of the following units (A) with crosslinkable side groups, and then crosslinking the crosslinkable side groups:
- in which
- X independently at each occurrence is a methylene group or oxygen,
- R independently at each occurrence is a methyl group or hydrogen,
- L1 is a divalent group which connects the polymer chain to the side group, and
- L2 is a divalent group which connects the polymer chain to the side group.
