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 A series of new poly(bismaleimide‐diamine)s (3a–c) with crown‐ether groups in the main chain were synthesized from bismaleimides (1a–c) and a diamino‐functional dibenzo‐18‐crown‐6 (2). The polymerization occurred in solution through the addition of the NH2 groups of 2 to the CC double bonds of the maleimide rings of 1. The optimum polymerization conditions were established. The polymers 3 were obtained in good yields and fairly high molecular weights (ηred = 0,15–0,35 dL/g). The polymeric crown eithers show high capacity for the binding of alkali metal ions and may be used as selective sorbents.
