摘要：

The SANS data for binary random poly(ethylene-butene-1) blends are analyzed using the lattice cluster theory (LCT) which relates bulk polymer properties to repeat-unit structures. The random poly(ethylene-butene-1)chains are approximated as monodisperse homopolymers. LCT repeat-unit interaction energies epsilon, epsilon11, and epsilon22 are fitted to the Flory chi parameters obtained from the SANS experiments. The calculated chi parameters have the correct temperature dependence, and the predicted UCST's agree with the experimental data.
