Relaxation Spectrum of Macromolecule Which from Experiment Data

摘要：

We have acquired the approximate method about how to get macromolecules relaxation spectrum by means of experiment data. Depending on steady state stress relaxation experiment or dynamic shear experiment, we have gotten steady state relaxation modulus function G(t) or dynamic state modulus function G1 (ω) and G//( ω ) . And then we have calculated all the approximate solutions of relaxation spectrum H ( X ) . Depending on the melt storage modulus G(ω) data and power cost modulus G(ω) data which from dynamic linear small swing shear oscillating experiment, we have calculated discrete relaxation spectrum in accordance with the approximate formulas which proposed by Schwarzl and staverman. At last, we also have discussed the affection of discrete relaxation spectrum which caused by some parameters and temperature.
