Description

  The present invention comprises a thermoplastic polymer composition that is excellent in impact resistance, antistatic property, and sustainability of antistatic property, and further has little change with respect to antistatic humidity, and this thermoplastic polymer composition. It relates to molded products.

    Thermoplastic polymers such as polyolefin resin, styrene resin, aromatic polyester resin, polyamide resin, acrylic resin, vinyl chloride resin, polycarbonate, etc. are excellent in mechanical properties, physical properties, moldability, etc. It is used in a wide range of fields such as vehicle field, electrical / electronic field, OA / home appliance field, building material field, sanitary field. However, because it has the disadvantage of being easily charged, it is used for various parts, sheets, films, etc. used in liquid crystal display devices, semiconductor peripherals, plasma displays, clean rooms, etc. It is difficult to do.

  In order to solve the above problems, for example, a composition in which a surfactant, conductive carbon, metal powder, conductive fiber and the like are blended with vinyl chloride resin is known (Patent Documents 1 and 2). However, when a surfactant is blended, there is a problem that antistatic properties are difficult to be exhibited and that antistatic durability cannot be obtained. On the other hand, when conductive carbon, metal powder, conductive fiber, or the like is blended, there is a problem that these conductive substances fall off and cause sparks to damage parts and the like.

  As a method for solving the above-mentioned problems, a composition in which a block copolymer comprising a polyolefin block and a hydrophilic polymer block as an antistatic agent is blended with a polyolefin-based resin has been proposed (Patent Document 3). A composition in which a specific polyamide elastomer is blended as an antistatic agent with a styrene resin has been proposed (Patent Documents 4 and 5). However, these compositions do not have problems such as antistatic durability and spark, but have problems that the antistatic properties are not sufficient and that the electrical properties are highly dependent on humidity.

  Further, an antistatic resin composition in which an ionic compound that is liquid at room temperature is blended with a thermoplastic resin has been proposed (Patent Document 6). However, usually, when an ionic compound that is liquid at room temperature is blended with a thermoplastic resin, there is a problem that antistatic properties are hardly exhibited. An ionic compound that is liquid at room temperature is also called “ionic liquid” or “room temperature molten salt”.
