均聚物液体的动态物理性质通过聚合物链在其维度上的全局运动而松弛。这一动议受到多种因素的影响。对于高分子量（M）链，缠结延迟的整体运动，影响性能。这种缠结效应随着链结构以及分子量分布而变化。链结构对全局链动力学的影响也被发现为非纠缠低M链以及。本文对这些效应的实验事实和分子解释进行了非常简要的总结。
Dynamic physical properties of homopolymer liquids relax through global motion of the polymer chains over their dimension. This motion is affected by a variety of factors. For high molecular weight (M) chains, the entanglement retards the global motion to affect the properties. This entanglement effect changes with the chain architecture as well as the molecular weight distribution. The effect of the chain architecture on the global chain dynamics is found also for non-entangled low-M chains as well. This article gives a very brief summary of the experimental facts and molecular interpretations for these effects.
