The composite material is obtained by adhering a low dielectric resin composition with phosphorus-containing flame retardant onto a substrate; the composition comprises the following components: (A) phosphorus-containing flame retardant; (B) vinyl compound. The phosphorus-containing flame retardant has a structure as shown in formula (I). In the present invention, diphenylphosphine oxide is derivatized, and prepared a phosphorus-containing flame retardant, which has no reactive functional groups, has better dielectric properties, and has high melting point, and upon combining with a vinyl compound, a resin composition is obtained, and a composite material having low thermal expansion ratio, high heat resistance, high glass transition temperature, and low dielectric constant and dissipation factor, can be made from the resin composition, and a laminate and printed circuit board having the properties of high glass transition temperature, low dielectric properties, halogen-free flame retardancy, low thermal expansion coefficient of the laminate, etc., can be made from the composite material.

Abstract: Formaldehyde-free binder compositions are described that include an aldehyde or ketone, a reaction product between a polyamine and an organic anhydride, and an acidic compound. The acidic compound may be an organic acid, an acidic catalyst, or both. The acidic compound is supplied in quantities that lower the pH of the binder composition to about 5 or less. The binder compositions may be used in methods of binding fiberglass and the resulting fiberglass products have an improved tensile strength due to the addition of the acidic compound.
