    摘要： This is to provide a multilayer tube excellent in interlayer adhesiveness and durability thereof while maintaining various characteristics such as low temperature impact resistance, bursting pressure strength and flexibility.
    In a multilayer tube having at least two kinds of layers and the both layers are adjacent to each other, an aliphatic polyamide composition constituting one of the layers contains an aliphatic polyamide having a ratio of a number of methylene groups to a number of amide groups of a specific value or more and a copolymerized polyamide having a specific unit, and an elastomeric polymer which may contain a constitutional unit derived from an unsaturated compound having a carboxyl group(s) and/or an acid anhydride group(s).

    摘要： This photocurable resin composition contains a polymer cross-linked material (A) and a polymeric material (B), wherein the polymer cross-linked material (A) contains urethane(meth)acrylate, and the polymeric material (B) contains a polyurethane resin that includes a structure derived from polycarbonate polyols and that does not have an acrylic group. This photocurable resin composition has excellent high-temperature adhesion. The urethane(meth)acrylate in the polymer cross-linked material (A) preferably includes a structure derived from polycarbonate polyols.

    摘要： The present invention pertains to a porous polyimide film production method and a porous polyimide film produced using said method, said method including: a step (1) in which a poly(amic acid) solution comprising 40%-97% by mass organic polar solvent and 3%-60% by mass poly(amic acid) having an intrinsic viscosity, comprising tetracarboxylic acid units and diamine units, of 1.0-3.0 is cast in film form and immersed in or caused to come in contact with a coagulating solvent having water as an essential component thereof, and a porous film of poly(amic acid) is produced; and a step (2) in which the porous film of poly(amic acid) obtained in said step is heat treated and imidized. Shrinkage in the film longitudinal direction and transverse direction after heat treatment is suppressed to no more than 8% for each direction and the speed of temperature increase in a temperature range of at least 200°C during the heat treatment is at least 25°C/min.
