Description

  The present invention provides a substrate having excellent electrical insulation characteristics, high strength, and excellent plating adhesion even in a high-temperature and high-humidity environment, suitable for plating formation by a three-dimensional circuit forming technique (LDS) method. The present invention relates to a polymer composition and a molded article comprising an alicyclic structure-containing polymer.

The alicyclic structure-containing polymer is suitably used as an electrically insulating material because of its low dielectric loss tangent.
In recent years, metal oxides that can form simple metal nuclei by irradiation with electromagnetic radiation are used for plating formation by a three-dimensional circuit forming technology (LDS) method, which can easily form finer circuits that are being put into practical use in recent years. A substrate material made of a synthetic resin such as polybutylene terephthalate is preferably used (Patent Document 1).
Moreover, when polycarbonate is used as a synthetic resin for the substrate material used in the LDS method, the polycarbonate is decomposed by the metal compound, the melt stability is lowered, and in order to solve the problem that processing becomes difficult, acrylonitrile-butadiene-styrene ( It has been proposed to blend a rubbery polymer such as ABS) (Patent Document 2). Here, it is described that it is desirable to blend titanium dioxide with polycarbonate in order to increase the deposition amount and adhesion strength of plating.
By the way, Patent Document 3 proposes a resin molding material excellent in both impact resistance and electric characteristics by blending a styrene-ethylene-propylene-styrene block copolymer rubber with a norbornene resin. .
