摘要:
[Problem to be Solved] The present invention has an object to provide an automotive lamp extension molding comprising a resin composition having a low specific gravity, being excellent in the balance of heat resistance and fluidity, and being excellent in gloss and brightness feeling of the surface of the molded article. [Solution] The automotive lamp extension molding according to the present invention comprises a resin composition comprising 50 to 95 mass% of a polyphenylene ether (A), and having a specific gravity in the range of 1.00 to 1.12. The reduced viscosity (measured at 30°C using a chloroform solvent) of the (A) component is preferably 0.25 to 0.45 dl/g, and more preferably 0.25 to 0.38 dl/g.

[Problem to be Solved] There is provided automotive lamp peripheral part excellent in the heat resistance, rigidity and fogging property. [Solution] The automotive lamp peripheral part according to the present invention is obtained from a resin composition containing 70% by mass or more of a polyphenylene ether (A), and has a haze value of a glass plate of 1.0% or less after the glass plate is subjected to a following fogging test using an apparatus according to ISO 6452: 60 g of a pellet or a molded article obtained from the resin composition is put in a glass-made sample bottle; the sample bottle is covered with a glass plate as a lid, and heated at 170°C for 24 hours to thereby generate fogging on the glass plate.

The present invention provides a membrane element, a gas separation device, and an internal combustion engine capable of improving gas separation performance. A gas separation device 1 including membrane elements 2 includes rigid members 32 arranged in a direction intersecting folds of a pleated structure 26 in open regions R1 and R2 of the pleated structure 26 surrounded by a reinforcement frame 27. The open regions R1 and R2 are each separated into a supply region and an exhaust region of gas by an elastic epoxy resin adhesive S provided between the rigid member 32 and the pleated structure 26.
摘要:
The present invention relates to a reaction method comprising a step of supplying a liquid containing at least one raw material compound and a low-boiling compound having a standard boiling point lower than a standard boiling point of the raw material compound to a flow channel, a step of heating the liquid to produce a liquid reaction product and a gas component by a reaction of the raw material compound, and a step of separating a liquid phase containing the reaction product from a gas phase containing the gas component and the low-boiling compound.
