Abstract

A new difunctional monomer (the divinylether of tetraethylene glycol) has been synthesized from the inexpensive and readily available tetraethylene glycol and acetylene. The monovinyl ether, however, is obtained with the literature procedure as the major product. While attempted polymerization of the latter with BF3.OEt2 gave mainly an oligomeric acetal, the divinyl ether gave an insoluble gel which is presumed to possess mainly a cyclized structure along with random cross-links. This polymer displayed phase transfer catalytic activity comparable to that of 18-crown-6 with NaCN in the nitrile substitution of hexylbromide, while with KCN it was less active than the crown ether. The oligomeric acetal did not catalyze this reaction significantly.
