Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract Dianhydrides of alicyclic tetracarboxylic acids were synthesized by chemical modification of tri‐cyclodecenetetracarboxylic dianhydride and its chloro‐containing derivatives. By polycondensation of these di‐anhydrides with diamines polyimides were obtained. Thermal and thermooxidative degradation of these polyimides are discussed. By the interaction of polyamic acid carboxylic groups with diamines in presence of phosphorus pentoxide a number of polyimidoamidines have been synthesized, some physico‐chemical properties of them are studied.
