    • This article reviewed most of the available theoretical models on the subject of chain entanglement. The present work only focused on linear flexible polymers that the various models intend to describe, leaving out semiflexible and rigid polymers whose entanglement condition may require a different set of considerations

    • To enjoy maximum conformational entropy, a chain, however long, does not become self-entangled. The concept of self-entanglement is experimentally relevant when the entire macroscopic sample is made of one giant linear molecule whose statistics cannot be Gaussian by definition. Here one may ask as a theoretical question of whether the chain is self-entangled while satisfying the condition of space filling. The answer to this question is not entirely obvious: we do not know whether such a chain would exhibit an identical level of elastic plateau to that of a realistic multiple-chain melt of the same chemical structure. Even if such a single-molecular sample would possess a similar plateau modulus, it is unclear whether it would have comparable cohesive strength in resisting to large deformation and yield6 at comparable strain amplitude

    • A simple account of chain entanglement based on binary interactions is not generic enough to depict loss of entanglement in presence of strong flow. At least, one may also have to specify a critical angle between the entangling segments, below which the topological constraint is ineffective
