Abstract

Mercapto‐16‐crown‐5 was prepared starting from tetraethyleneglycol and 3‐chloro‐2‐chloromethyl‐1‐propene. Radical polymerization of methyl methacrylate was carried out in the presence of mercapto‐16‐crown‐5 as a chain transfer agent to give crown ether‐terminated poly(methyl methacrylate). The end crown group was characterized by IR and ^1^H‐NMR spectra. Sodium cation was selectively extracted by this crown‐containing polymer. The molecular weight of the obtained polymer had influence upon the ability of extraction of sodium cation.

Anthracene-labelled poly(methy1 methacrylate) (PMMA) was prepared via atom transfer radical polymerization (ATRP) where 9,10-bis(chloromethyl)anthracene and CuC1/2,2'-bipyridine were used as the initiator and catalyst, respectively. Both the linear increase of the number average molecular mass with
