Copolymerization experiments were performed by a liquid-liquid two phase, benzene/1.5 N NaOH (aq), phase transfer catalyzed reaction with tetrabutylammonium hydrogen sulfate (TBAH) or tricaprylmethyllammonium chloride (Aliquat 336) catalysts. A series of copolymerization experiments were performed with 1/2 molar ratios of 4/1, resulting in PPO-2OH with Mn in the range of 2200-3200 g/mol. Phase transfer catalyzed etherification of the PPO-2OH chain ends with p-chloromethylstyrene was used to synthesize α,ω-bis(vinylbenzyl ether)s of the PPO-2OH (PPO-2VBE). The chain microstructure and the fuctionality of both PPO-2OH and PPO-2VBE was studied by 200 MHz 1H-NMR spectroscopy.
