The conformation assumed by a polymer chain in dilute solution can be modeled as a random walk of monomer subunits using a freely jointed chain model. However, this model does not account for steric effects. Real polymer coils are more closely represented by a self-avoiding walk because conformations in which different chain segments occupy the same space are not physically possible. This excluded volume effect causes the polymer to expand. WebJunyuan Petroleum Group ᴾᵘʳⁱᵗʸ. Qᵘᵃˡⁱᵗʸ. ᵀʳᵘˢᵗ. 2024 年 1 月 - 至今6 年 4 个月. Dongying, Shandong, China.
