Grafting of thermotropic fluorinated mesogens on polysiloxane to improve the processability of linear low-density polyethylene

TSCPFLCP is a polysiloxane grafted with thermotropic fluorinated mesogens, which when blended with LLDPE reduces melt torque, broadens the processing window, ameliorates melt fracture, and enhances mechanical properties. The TSCPFLCP exhibits a smectic liquid crystal phase and high thermal decomposition temperature. These improvements are achieved at a low concentration of 0.5 wt% TSCPFLCP, indicating its effectiveness as a processing aid for LLDPE. The researchers were able to use a Linkam THMS600E stage to investigate the temperature-dependent texture of the polymer.

Flow-induced crystallisation of polymers from aqueous solution using Linkam’s CSS450

Researchers used Linkam’s CSS450 to replicate the mechanical properties of natural silk by creating a synthetic polymer that solidifies when subject to flow. Using temperature-controlled shear in the aqueous phase they induce polymer crystallisation, providing an alternative low-energy polymer processing route.
