Abstract
A self-avoiding polymer chain confined in a sphere is generated by Monte Carlo technique on a simple cubic lattice. The dependence of shape of polymer chain on concentration C of polymer solution is studied. The shape of polymer chain is denoted as 〈L12〉:〈L22〉:〈L32〉, where L1≤L2≤L3 are orthogonal components in the system of principal axes of gyration. At low concentration (C≤0.001), 〈L22〉/〈L12〉 and 〈L32〉/〈L12〉 remain approximately unchanged with the concentration. Then, with increase of the concentration, 〈L22〉/〈L12〉 and 〈L32〉/〈L12〉 decrease, and 〈L32〉/〈L12〉 decreases more rapidly than 〈L22〉/〈L12〉. Asymptotically, 〈L22〉/〈L12〉 and 〈L32〉/〈L12〉 become 1.0 at a concentration C=1.0.
