High‐Performance Polybenzoxazine Derived from Polyfunctional Benzoxazine Composed of an Oligonuclear Phenolic Compound Having a 4,4′‐Dimethylenebiphenyl Linker

Abstract

Front Cover: In article https://doi.org/10.1002/macp.201800317, Takehiro Kawauchi, Tsutomu Takeichi and co‐workers report that a novel polyfunctional benzoxazine yields a remarkably tough polybenzoxazine thermoset film with much improved thermal properties. The benzoxazine is synthesized using an oligonuclear phenolic compound which is commercially available as a curing agent for epoxy resin.
