The preliminary work involved binary blends of ethylene/norbomene random copolymers studied by NMR spectroscopy. The miscibility was observed for norbomene content >50 % where the microstructure changes due to side group crowding. The SLCT computations indicate that the chain stiffiiess significantly affects miscibility - the entropic contribution to x seems to be the controlling factor. Experimental miscibility diagrams agreed reasonably well with LCT predictions (Delfolie et al. 1999).

Metropolis Monte Carlo (MC) simulations (Allen and Tildesley 1987 Frenkel and Smit 2002) have been used to predict the structural and thermodynamic properties of mixtures of elemental semiconductors as also compound semiconductors. MC simulations have been conducted using both the VFF and Tersoff potential models to describe the interatomic interactions. The structural properties determined include lattice constants, thermal expansion coefQdents and bond lengths. The temperature versus composition miscibility diagram of ternary alloys at a given pressure, and the miscibility envelope for quaternary alloys at given temperature and pressure conditions have been determined using the transition matrix Monte C arlo (TMMC) method.

In this letter, we explore theoretically the conditions for homogenization of two mutually immiscible polymers by changing all the linear-polymer chains of one of the components by cross-linked polymer nanoparticles. Specifically, we consider the PS/poly(methyl methacrylate) (PMMA) pair as a model system. Im-miscibility between PS and PMMA is well known in the literature as a result of unfavorable interactions between styrene (S) and methyl methacrylate (MMA) repeat units [11-13]. Here, miscibility diagrams for PMMA-NP/PS nanocomposites are reported as a function of PMMA-NP size, PS molecular weight (Mn) and temperature. Finally, several nanoscale effects affecting the miscibility behavior of PMMA-NP/PS nanocomposites are also discussed.
