発明の名称
(EN) OIL RECOVERY AGENT, OIL DISPERSION, AND OIL RECOVERY METHOD
(FR) AGENT DE RECUPERATION D'HUILE, LIQUIDE DE DISPERSION D'HUILE, ET PROCEDE DE RECUPERATION D'HUILE
要約
(EN) The present invention provides an oil recovery agent that has properties for reducing the viscosity of oil and improving fluidity (viscosity reduction properties) and properties for quickly separating after dispersion in oil (immediate separation properties), and that enables quick recovery of oil. This oil recovery agent contains a polyvinyl-alcohol-based resin in which the water contact angle when the resin is formed into a film is 70° or smaller.
