摘要：
Monte-Carlo simulations were performed on concentrated systems of chains of 15 and 20 units on a tetrahedral lattice. The average second and fourth moments of the end-to-end distance were computed from these simulations. Both the second and fourth moments, when extrapolated to bulk concentration, were found to agree with ideal chain values. The scaling exponent for the concentration dependence of the second moment in the semidilute range, for these short-chain systems, was found to be less than the theoretical value of 1/4. © 1979, American Chemical Society.
