    摘要： 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 %, and wherein the weight ratio of the cyclic olefin copolymer (B) to the unsaturated monomer (A) is 0.5 to 7.

    摘要： Hot melt adhesive compositions which have enhanced adhesion to difficult substrates, particularly at refrigerator/freezer temperatures or at elevated temperatures. The inventive compositions require a base polymer comprising at least one metallocene ethylene-containing polymer or at least one non-metallocene, amorphous, propylene containing polymer; a tackifier; an optional wax; and an adhesion promoting additive comprising at least one semi-crystalline polymer having a weight average molecular weight of about 30,000 daltons or less. It has been found that the adhesion promoting additive of this invention enhances the adhesion properties of a hot melt adhesive composition having a metallocene ethylene-containing base polymer or non-metallocene, amorphous, propylene containing base polymer, particularly at elevated temperatures or at low refrigerator and freezer temperatures where other conventional adhesives have been unsuccessful.
