摘要：
The polymer reference interaction site model (PRISM) theory is applied to the study of tacticity effects in blends of poly(vinyl chloride) (PVC) and poly(methyl methacrylate) (PMMA). The single-chain structure factors required as input to the theory are computed using Monte Carlo simulations based on rotational isomeric state (RIS) statistical weights. The PRISM results agree with the observed experimental trends for the systems where data are available. The observed and predicted trends appear to arise from a competition between effects due to local conformations and those due to overall chain stiffness.
