Tuning Entanglement Molecular Weights with Ultrahigh-Molecular-Weight Polystyrenics

Tuning Entanglement Molecular Weights with Ultrahigh-Molecular-Weight Polystyrenics

We report a method to produce ultrahigh-molecular-weight (UHMW, >10<sup>6</sup> Da) styrenic polymers with tunable entanglement molecular weights (<i>M</i><sub>e</sub>). The high number of primary chain entanglements (≫10) results in good mechanical strength an...
