Abstract
A polyimide includes a non-crosslinked structure including a main chain. The main chain includes a Si—O—C bond. The main chain may include a C—O—Si—O—C bond. The main chain includes, for example, a group denoted by —OSi(R1)(R2)O—. At least one oxygen atom included in the group bonds to, for example, a carbon atom adjacent to the group to form the Si—O—C bond.
Claims14
A polyimide comprising:
- a non-crosslinked structure including a main chain,

A polyimide comprising:
- a main chain including a Si—O—C bond,
- wherein a ratio of the number of silicon atoms included in the main chain to the number of imide groups included in the main chain is greater than or equal to 2% and less than or equal to 50%.
