The synthesis of 4′-vinylbenzo-12-crown-4 ether is reported. Polymerization to relatively low molecular weight polymers can be accomplished with a free radical initiator. A copolymer with styrene can be prepared and the Li+, Na+, and K+ binding properties of these polymers are compared to those of their monomeric analogs using salt distribution equilibria in water – methylene chloride. For all cations the homopolymer is found to extract the salts from the aqueous phase most effectively. The copolymer is slightly less effective than the homopolymer but more effective than either of the monomers by a factor of approximately 7, indicating that cooperative binding is likely. Na+ is the most efficiently extracted cation, followed by K+ and Li+. Key words: crown ether polymers, complexation properties.

Enzymatic Depolymerization

1. The presence of mucopolysaccharides within arterial walls may be associated with the high concentration of sodium ions within this tissue. These polyanions are sensitive to enzymatic depolymerization which results in a loss of the cation binding properties of the molecule. 2. In this study testicular hyaluronidase perfused through isolated arterial segments resulted in a decrease in reactivity of the artery to 65% that of control arteries. Associated with this finding was a 33% decrease in the sodium ion content of the stimulated hyaluronidase-treated artery. When a variety of other sympathetically innervated tissues were treated with hyaluronidase there was no decrease in reactivity or sodium ion content.
