Synthesis and Extraction Study of Calix[4]Arene Dinitrile Derivatives Incorporated in a Polymeric Backbone with Bisphenol-A. Journal of Polymers and the Environment, 9(2), 97-101.

The phase transfer studies were performed by using liquid-liquid extraction procedures. It has been deduced from the observations that both copolymers show a good phase transfer affinity toward selected alkali, alkaline earth, and transition metal cations, unlike their precursor (3).en10.1023/A:1020256907414info:eu-repo/semantics/openAccesscalixarenecopolymerliquid-liquid extractionphase transferalkali, alkaline earth, and transition metal cationsArticle9297101WOS:000177985700006Q4
