Preparation of Poly[(ether)-(ether ether ketone)] Dendrimers by the Convergent Method [PDF]

open access: yesPolymer Journal, 2000
New highly branched poly[(ether)-(ether ether ketone)] dendrimers were synthesized by the convergent approach using two building blocks, 3, 5-dihydroxybenzyl alcohol, 1, and 3, 5-dihydroxy-4′-(4-fluorobenzoyl)diphenylether, 2, alternatively. The reaction of p-fluorobenzonitrile and 1 gave 3, 5-di(4-cyanophenoxy)benzylalcohol (the first generation ...
