摘要：

The relative magnitude of the equilibrium constants describing self-association versus inter-association is an important factor in determining the phase behavior of polymers that hydrogen bond. In studies of sterically hindered phenolics we have found that poly(2,6-diisopropyl-4 vinylphenol) (PDIPP) only moderately self-associates, but strongly inter-associates with polymers containing groups such as ester carbonyls, ether oxygens, and the like. PDIPP is miscible with polytetrahydrofuran (PTHF) and simultaneously acts as an efficient polymeric antioxidant. This result points the way to the design of specific miscible polymeric antioxidants for polar polymers.
