PURPOSE:To provide the titled polyolefin which is suitable for the pipes of vacuum cleaners and exhibits antistat effect over a long period of time following the production, by adding a polyoxyethlene alkylamine as an antistatic agent together with a tallow-ethylene oxide adduct to a polyolefin. CONSTITUTION:A polyoxyethylene alkylamine, which exhibits durable effect as antistatic agent over a long period of time, and a tallow-ethylene oxide adduct, which rapidly exhibits the effect, are added to a polyolefin such as polypropylene. By this addition, antistat effect is noticeable immediately after blow molding and the effect is semipermanently maintained. Thus, when the produced is used for the pipe of a vacuum cleaner, the deposition of dust immediately after molding is prevented and the deposition of dust during the use of the vacuum cleaner is also prevented. Further, a phenomenon which involves an electric shock to a fingertip can be prevented. |
