Although disentangled polymers obtained through specialized methods can partially mitigate this issue, the instability of disentanglement and the ambiguous kinetics of spontaneous re-entanglement render practical application difficult and poorly controllable. Herein, we report a strategy that addresses this conflict by introducing cleavable crosslinker into soft-nanoparticles (SNPs), enabling a controlled transition from a disentangled state stabilized by crosslink to re-entangled state upon external triggering. A disulfide-containing divinyl crosslinker was designed and synthesized, and cleavable polystyrene SNPs with diameters of 13–30 nm were prepared by microemulsion polymerization. When treatment with 1,4-dithiothreitol, the disulfide bonds at the crosslinking points are selectively cleaved, converting the SNPs into linear chains that subsequently undergo re-entanglement. These SNPs exhibit typical soft-colloidal dynamics with viscosities markedly lower than those of their linear counterparts, consistent with previous studies. Rheological measurements demonstrate that crosslinker cleavage restores the plateau modulus and characteristic relaxation scaling of entangled polymers, confirming the recovery of a highly entangled state. Moreover, a viscosity contrast of one to two orders of magnitude is observed before and after cleavage, even at high degrees of entanglement. These findings establish that cleavable SNPs can serve as stable low-viscosity processing precursors while retaining the capacity to regain mechanical performance after re-entanglement, offering a new strategy for reconciling processability with the mechanical integrity associated with high entanglement.</div></div>","PeriodicalId":405,"journal":{"name":"Polymer","volume":"365 ","pages":"Article 130903"},"PeriodicalIF":5.1,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149091696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
