A prepreg is provided. The prepreg is prepared by impregnating a liquid crystal polymer non-woven fabric with a thermal-curable resin composition or by coating a thermal-curable resin composition onto a liquid crystal polymer non-woven fabric and drying the impregnated or coated liquid crystal polymer non-woven fabric, wherein the thermal-curable resin composition comprises: (A) an unsaturated monomer; and (B) a cyclic olefin copolymer comprising the following repeating units: (B-1) a repeating unit of formula (I), n n(B-2) a repeating unit of formula (II), n ; and n(B-3) a repeating unit of formula (III), n nR 1 to R 22 , m, n, o, and p in formulas (I) to (III) are as defined in the specification, wherein based on the total moles of the repeating units (B-1) to (B-3), the content of the repeating unit (B-2) is 19 mol% to 36 mol%, and wherein the weight ratio of the cyclic olefin copolymer (B) to the unsaturated monomer (A) is 0.5 to 7. |
