Abstract
A carbonate esther film contains a plurality of repeated carbonate esther main bond as indicated in the formula (1), the level of the molecular weight from the formula (1) is 0.01-5 mole% which is to be formed by selecting isobond unit of carbonate esther from the formula (2) below, (in which Ar is two valence C5-C200 aryl, Ar^ is three valence C5-C200 aryl and Ar" is four valence C5-C200 aryl, X represents a repeated unit of carbonate esther bond having a mean molecular weight of 214-100,000 as shown in the following formula, Y represents a repeated unit of carbonate esther bond having a mean molecular weight of 214-100,000 as shown in the following formula.)
