Abstract

The invention provides a thermosetting resin composition comprising a prepolymer of a diallyl compound and a maleimide compound, wherein the structural formula of the diallyl compound is shown as a formula (1) described in the specification; R1 is -C (CH3)2, -C (CF3)2, -SO2, -CH (CH3), -CH2 or an oxygen atom; R2 and R3 are same or different aliphatic hydrocarbon with the carbon number below 10 or aromatic hydrocarbon with the carbon number below 30; the R2 and the R3 contain no allyl group. The thermosetting resin composition has the advantages of good heat stability and heat and humidity resistance, low dielectric constant and dielectric loss angle tangent and excellent process machinability. The embodiment of the invention further provides applications of the thermosetting resin composition to resin sheets, resin composite metal foils, prepregs, laminated boards, metal foil clad laminates and printed circuit boards.

Description

technical field [0001] The present invention relates to a resin composition, in particular to a thermosetting resin composition and its application in resin sheets, resin composite metal foils, prepregs, laminates, metal foil-clad laminates and printed circuit boards . Background technique [0002] In recent years, with the development of high-performance, high-functionality and networking of information and communication equipment, in order to transmit and process large-capacity information at high speed, the operation signal tends to be high-frequency. At the same time, in order to meet the development trend requirements of various electronic products , the circuit board is developing towards the direction of high multi-layer and high wiring density, which requires the substrate material not only to have good dielectric properties (low dielectric constant and low dielectric loss tangent) to meet the needs of high-frequency signal transmission, but also requires It has goo...
