PPPoE

(Point-to-Point Protocol Over Ethernet) PPPoE enables a point-to-point connection in the normally multipoint architecture of Ethernet. A discovery process in PPPoE determines the physical MAC address of the remote device in order to establish a session. See PPP, Ethernet and PPPoA.

PPO was dissolved in NaOH solution to form phenolate anion and PPOE was synthesized by ring-opening reaction between phenolate anion and EPN.
PPOE, [sup.1]H NMR, [delta] (ppm): 7.13-6.68 (m, Ar-H of terminal PPO away from Ar-OH and Ar-H of EPN segment), 6.46-6.35 (s, Ar-H of internal PPO), 4.30 (s, Ar-OH of terminal PPO), 4.19-3.71 (m, -C[H.sub.2]-), 3.65 (s, -CH-), 3.53 (s, hydroxyl proton of -CH-OH), 3.28, 2.85, 2.70 (m, H of epoxy group), 2.19-2.02 (s, Ar-C[H.sub.3] of PPO).
The two peaks of PPO segment in PPOE keep consistent with that of PPO, and the ratios of integral values between peak c and b are 3.19 and 3.17, respectively.
In addition, The [M.sub.n] of PPO and PPOE could be estimated by both NMR and GPC, as summarized in Table 2, the [M.sub.n] values evaluated from NMR are consistent with those measured via GPC.
PPOE with multiple epoxy groups on its end obeyed the same rule when got involved in the curing reaction.
