A circuit board includes an insulating made by a low dielectric resin composition includes a low dielectric resin containing acid anhydride, an epoxy resin, polyphenylene ether resin with vinyl and active esters, maleic acid liquid polybutadiene, and an accelerator. Such low dielectric resin can be dissolved in organic solvent more easily than a low dielectric resin without acid anhydride, and the low dielectric resin containing acid anhydride has a better compatibility with other organic components than a low dielectric resin without acid anhydride. A low dielectric resin composition with lower dielectric constant and better properties can thus be obtained.

The present invention provides a resin composition having superior flexibility and that exhibits excellent durability in thermal molding, and a molded body of such a resin composition. The present invention relates to a resin composition comprising: a copolymer (B) constituted of a vinyl alcohol polymer (B-1) region and a diene polymer (B-2) region; and at least one compound selected from the group consisting of a phenol-based compound (C), an amine-based compound (D), and a phosphorus-based compound (E).

The present disclosure provides a thin film including a first thermoplastic polyolefin (TPO) elastomer which is anhydride-grafted. The present disclosure further provides a method for manufacturing the thin film, a laminated material and a method for adhesion.

The present invention is directed to a new class of thermoplastic elastomers (TPEs) and processes for making them. In some embodiments of the present invention, the end groups of the multi-arm PIB copolymer is a conjugated diene, whereas the other component is a multi-functional dienophile. The components of the TPE of the present invention are chemically connected via the well-known Diels-Alder reaction which is thermally reversible (by the retro-Diels-Alder reaction) at moderately elevated temperatures. The reversibility of the Diels-Alder retro-Diels-Alder reactions allows the recovery of the original components of the TPE and thus its recyclability and also gives the TPE the ability to be reshaped or reformed.
