Abstract
A halogen-free resin composition and a method for preparation of copper clad laminate with the same, wherein based on total parts by weight of solid components, the halogen-free resin composition comprises a reactive allyl phenoxy cyclotriphosphazene or vinyl phenoxy cyclotriphosphazene of 5-50 parts, a thermosetting resin of 15-85 parts, a crosslinking curing agent of 1-35 parts, a crosslinking curing accelerant of 0-5 parts and a filler of 0-100 parts. In the present invention, the reactive allyl phenoxy cyclotriphosphazene or vinyl phenoxy cyclotriphosphazene having very low water absorption is introduced into the thermosetting resin, satisfying both the halogen-free and antiflaming requirements and improving the electrical properties of the system, and making it possible to prepare the halogen-free high-frequency high-speed substrate material. The resulted copper clad laminate satisfies the halogen-free requirement, and has advantages such as excellent resistance to heat and moisture, and low dielectric loss.
