As a molded article that has gas barrier properties even if a gas barrier layer is not provided and that also has molding stability and biodegradability, there is proposed a molded article containing an aliphatic polyester-based resin (A) and a polyvinyl alcohol-based resin (B) as main component resins, wherein the molded article has a resin phase-separated structure having a continuous phase including the aliphatic polyester-based resin (A) as a main component, and a ribbon-like dispersed phase including the polyvinyl alcohol-based resin (B) as a main component.

Molded article and method for producing molded article

A diverting agent and method for temporarily filling fractures. The diverting agent contains a powder-like polyvinyl alcohol-based resin (P1) and a pellet-like polyvinyl alcohol-based resin (P2), and has an adsorption coefficient kc of 0.01 or more and 1 or less.

Diverting agent, method for temporarily filling fracture in well using same, and method for further forming fracture

A diverting agent which has performance to release filling due to biodegradability, can be quickly removed after a certain period of time, and has an excellent filling property with respect to a fracture in a well is provided. The diverting agent contains particles having a particle diameter of 1,700 μm or more in an amount of 10 to 70 mass %, particles having a particle diameter of 500 μm or more and less than 1,700 μm in an amount of 20 to 80 mass %, and particles having a particle diameter of less than 250 μm in an amount of 5 to 40 mass %, and the diverting agent contains a biodegradable resin in an amount of 10 mass % or more.
