Abstract
Description
technical field
[0001] The invention describes a method for preparing polybenzoic acid by using pentafluoroantimonic acid catalyst method of oxazine. Background technique
[0002] Benzo oxazines and benzos Compositions of Benzoxazines are known (see e.g. U.S. Pat. Resins (based on benzo Development of a new class of electronic packaging materials of the ternary system of oxazine, epoxy resin and phenolic resin)", Polymer, 41, 7941-49 (2000); and H.Kimura et al., "New Thermosetting Resin from Bisphenol A- based Benzoxazine and Bisoxazoline (from bisphenol A-based benzoxazine zine and bis Novel thermosetting resins of oxazolines), J. App. Polym. Sci., 72, 1551-58 (1999).
[0003] US Patent 7,517,925 (Dershem et al.) describes benzo oxazine compounds and benzos A thermosetting resin composition prepared from an oxazine compound. The composition is said to be useful for increasing adhesion at interfaces within microelectronic assemblies with reduced shrinkage a...
