20230045848 · 2023-02-16 ·

Provided are a thermosetting resin composition and a prepreg, laminate and printed circuit board using same. The thermosetting resin composition comprises a resin component, the resin component comprising a modified cyclic olefin copolymer having a structure as shown in formula I and another unsaturated resin. By introducing a methacrylate end group having a certain polarity into a cyclic olefin copolymer, a modified cyclic olefin copolymer is formed. The modified cyclic olefin copolymer can form a thermosetting material by means of cross-linking with itself or another unsaturated resin, whereby the bonding property can be significantly improved while retaining the excellent dielectric properties of the cyclic olefin copolymer itself. The laminate prepared using the thermosetting resin composition has good dielectric properties, a good peel strength and a good heat resistance, and can meet all the performance requirements for printed circuit board substrates in the current high-frequency and high-speed communication field.

PLASTIC FILM AND A METHOD FOR MANUFACTURING SAME

The present invention relates to a plastic film and a method for manufacturing same. A plastic film, which is formed such that at least one part has a curved shape, can have high hardness, impact resistance, scratch resistance and high transparency. The plastic film is light and will not be easily damaged by external pressure and thus can substitute for the existing glass and is expected to be used for various electronic products such as a display and the like. In particular, the plastic film has at least one part in a curved shape and thereby is expected to be used for products in various shapes which cannot be manufactured by means of the existing glass. Moreover, a method for manufacturing a plastic film enables manufacturing of a plastic film having at least one part in a curved shape without curls or cracks as well as simultaneous performing of heat molding and heat curing, thereby increasing the productivity of a plastic film.
