| Abstract: | A linear phenolic polymer has been prepared by condensing p-bromophenol with formaldehyde in the presence of a catalyst. The linear polymer was dehalogenated completely by a standard procedure. Some oligomers of uniform structure and molecular weight were grafted on the dehalogenated polymer. Electrometric titration curves of the grafted copolymers have been studied, and the shape of the titration curves has been interpreted in terms of the length of the grafted chain and the intramolecular H-bonding between neighbouring OH groups. |
