ABSTRACT:
A dianhydride is converted into an alcohol-soluble di-ester and subsequently used to form a lacquer with a mixture of a diamine and an aminoarylacetylene. When the solvent is removed and the mixture of compounds is heated to a curing temperature a cured acetylene-end-capped polyimide polymer is produced.
