Abstract
Cyanate ester polymer articles, particularly fiber-reinforced, are metallized by electroless deposition preceded by a series of pretreatment steps which improve adhesion of the metal layer or layers. Said steps include aqueous alkali followed by nitric acid treatment. They preferably also include an initial alkaline permanganate treatment, preferably preceded by aqueous alkali.
