Abstract
A method of preparing a film-forming polyphenylene oxide (PPO) composition as well as a laminate using such composition, wherein a setting means selected from the group consisting of a crosslinking monomer, a crosslinking polymer, and mixtures thereof, and, optionally, an initiator are added to and mixed with PPO, and a sufficient film-forming property is provided to PPO by allowing the setting means and, if present, the initiator to crosslink, whereby the PPO composition has the ability to form a film. Further, when a plurality of such films are stacked and integralized to form a melt-clad laminate, the laminate exhibits low dielectric constant and loss, so as to be used effectively in superhigh frequency bands such as the X band used for satellite communication.
