Morphological Studies of Solution-Crystallized Thermoplastic Elastomers with Polyethylene Endblocks and a Random-Copolymer Midblock

Yan, J., Lee, B., Smith, S. D., & Spontak, R. J. (2021, September 22). MACROMOLECULAR RAPID COMMUNICATIONS, Vol. 9.

By: J. Yan n , B. Lee *, S. Smith* & R. Spontak n 

author keywords: block copolymers; directed self-assembly; polymer morphology; solution crystallization; thermoplastic elastomers
MeSH headings : Crystallization; Elastomers; Polyethylene; Polymers; Temperature
TL;DR: According to transmission electron microscopy, semi-crystalline aggregates develop at the lowest solution concentration examined (0.01 wt%), and the size and population of crystals, which dominate the copolymer morphologies, are observed to increase with increasing aging time.

Ionic Complexation of Endblock-Sulfonated Thermoplastic Elastomers and Their Physical Gels for Improved Thermomechanical Performance

Journal of Colloid and Interface Science, 2.

By: J. Yan n , S. Yan  n, J. Tilly n, Y. Ko  n, B. Lee * & R. Spontak  n

author keywords: Thermoplastic elastomer; Thermoplastic elastomer gel; Physical gel; Block ionomer
TL;DR: S sulfonate and subsequently complex (and physically crosslink) the endblocks with trivalent Al3+ ions, which reduces the effective hydrophilicity of the sulfonated endblocks, as evidenced by water uptake measurements, while concurrently enhancing the thermomechanical stability of the corresponding TPEGs.
