| Abstract: | With the conformational statistical method theory and the improved rotational isomeric state model of large side groups, the mean_square radius of gyration of the symmetrically substituted polymer chain are deduced, by which the flexibility of poly(dimethylsilmethylene) (PDMSM) may be investigated. According to the formula of ratio vs. chain length, the ratio of the large PDMSM are calculated 0 94, which is compared with that of poly(dimethylsiloxane) from our previous calculation. |
