摘要： The present invention refers to a polymer composite that comprises sand preferably medium, at least a load, at least a resin selected from among dicyclopentadiene polyester resin (DCPD) and resin PET and at least a phase-compatibilizing additive and/or flexibilizing agent of the polymer structure. Further, the present invention refers to process of preparing said composite besides the use of said composite for preparing some articles including sleepers. This composite presents several advantages when compared to the materials used today for preparing sleepers as it is more versatile than steel, more available and as effective as wood, more durable than the concrete as it comprises an optimized composition that combines ideal physical-chemical properties to exercise the function for which it was intended.

摘要： 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.
