We report the results of experimental infrared and thermal analysis studies of binary miscible blends of poly(vinyl methyl ether) (PVME) with an ethyl methacrylate‐co‐4‐vinyl phenol (EMAVPh) copolymer. This is a complex blend system, involving multiple specific interaction sites. Using the concept of competing equilibria we show that the equilibrium constant describing hydrogen bonding between the OH group of EMAVPh and the ether oxygen of PVME can be determined from quantitative infrared spectroscopic analysis of the fraction of hydrogen bonded carbonyl groups present in miscible binary blends.
