摘要: We present a novel Monte-Carlo lattice model for the study of coil-stretch transition polymer chains in deformation flows. Our results indicate that elongational flows are much more effective than shear stretching chains, full agreement with experimental observation. data also show e˙c∼M−1.5 powerlaw observed experimentally dependence critical flow rate on molecular weight can be fully explained through nonuniform chain by flow. A higher exponent is predicted affine cases. © 2000 John Wiley & Sons, Inc. J Polym Sci B: Phys 38: 2422–2428,
