Flexible prepreg and uses thereof

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 polym...

Beschreibung
Zusammenfassung:	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 includes:(A) an unsaturated monomer; and(B) a cyclic olefin copolymer including the following repeating units:(B-1) a repeating unit of formula (I),(B-2) a repeating unit of formula (II),and(B-3) a repeating unit of formula (III),R1 to R22, 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 %, andwherein the weight ratio of the cyclic olefin copolymer (B) to the unsaturated monomer (A) is 0.5 to 7.
