摘要: Description of four new silicon-containing dianhydrides synthetized in an attempt to provide useful polyimide precursors. They were prepared by aqueous potassium permanganate-pyridine oxidations corresponding tetramethyl intermediates form tetracarboxylic acids, which dehydrated the dianhydrides.
