NEW REACTIVE POLYETHERS - PREPARATION AND SYNTHETIC POSSIBILITIES

Starting from 4-methoxycarbonylphenyl glycidyl ether and unfunctionali zed phenyl glycidyl ether, samples of highly regio- and stereoregular linear homo- and copolymers were synthesized using the ionic coordinat ive initiator system aluminium isopropoxide/ZnCl2. The polymers were f irst transformed into carboxylic acid derivatives and then into highly reactive carboxylic acid chlorides with high yields and conversions. The use of all these synthesized polymers was tested by transforming t hem into the corresponding 4-nitrobenzyl ester using different synthet ic procedures. Finally, the scope of the methodology studied was teste d by using it to synthesize a set of new polymers containing different complex groups such as: 18-crown-6, biphenyl-4-carbonitrile, anthraqu inone, (1R)-nopol, (-)-inosine and 4-dodecylaniline, which are in gene ral obtained with good yields and conversions.
