METHOD OF ANALYZING MOLECULAR MOTION OF MIXTURE COMPRISING DIFFERENT MOLECULES AND ANALYSIS PROGRAM

In a method of analyzing the molecular motion of a mixture comprising different polymer materials, the polymers of the mixture comprising different polymer materials to be analyzed are roughly visualized depending on the molecular weights among tangling points according to the reptation theory. Based on the intertube factor constituting each polymer thus formed, the position coordinate, the alignment vector, the number of monomers in the tube factor and the tube factor of the counterpart forming the tangling are time developed per the unit time as defined by the formula 7 in accordance with Langevin formula defined by the formula 1 (step 201). Then the number of monomers in the tube factor is time developed in accordance with the formula 5 (step 202) and the number (n) of monomers in the tube factor at each terminus of the polymer is monitored. In accordance with the formula 8, the tube factor of the counterpart forming the tangling is altered.
