Abstract
Abstract A functional polymer having a main chain of carbon-carbon bonds and at least one functional group appended to the main chain with intervention of a carbonyliminocarbonyl linkage, the functional group being any one chosen from the group consisting of a fluorinated group, an aminotriazine group, a photosensitive group and a bicyclo or spiro structure group and the content of the functional groups including the carbonyliminocarbonyl linkage in the molecule of the functional polymer being from 0.1 to 99.9% by weight.
