Abstract:
The SANS data for binary random poly(ethylene-butene-l) 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 ε, εll, and ε22 are fitted to the Flory X parameters obtained from the SANS experiments. The calculated X parameters have the correct temperature dependence, and the predicted UCST's agree with the experimental data.
