Abstract
There are disclosed polybenzoxazole precursors which can be processed by centrifugal techniques, which can be cyclized to polybenzoxazoles on substrates without difficulty, and which after cyclization to polybenzoxazoles exhibit a high temperature stability. In particular, these precursors and the polybenzoxazoles prepared from them possess high resistance against the diffusion of metals.
