APPARATUS AND METHOD FOR MEASURING MOLECULAR MOVEMENT OF POLYBLENDS

摘要

PURPOSE: An apparatus and a method for measuring molecular movement of polyblends are provided to reduce costs and improve safety by increasing the pressure difference through the use of vacuum. CONSTITUTION: An apparatus comprises a six-branch flange(1) connected to a specimen mounting flange(2) having a window(3); a pressure measuring unit(6) attached to the six-branch flange; a vacuum pump(5) mounted in the lower portion of the apparatus so as to maintain the interior of the apparatus at a vacuum state; a valve(4) interposed between the six-branch flange and the vacuum pump; and a temperature control unit attached to each specimen mounting flange so as to allow experiment to be performed over a wide range of temperature.
