Research paper #2 from our group just dropped as Open Access in Adv Materials. In this paper, we probe pendant length in frontal polymerization and the resulting material properties. @KA_Stew absolutely crushed this one, check it out! @JacobJLessard1 advanced.onlinelibrary.wiley…

Engineering Free Volume within Frontal Ring‐Opening Metathesis Polymerization via Pendant Plastic...

Norbornene-based copolymers with tunable n-alkyl pendant length provide control over matrix free volume, enabling elastomeric materials via frontal ring-opening metathesis polymerization (FROMP).

Crispy new paper out now in @ChemicalScience! @cabelleades27 and pals used aqueous PISA as a tool to avoid high viscosities typically obtained during UHMW polymer synthesis! Also got some massive polymer microparticles in the process. @Brent_Sumerlin tinyurl.com/SaltyPISA

Ultra-high molecular weight polymer synthesis via aqueous dispersion polymerization†

The synthesis of ultra-high molecular weight (UHMW, Mn ≥ 106 g mol−1) polymers is generally complicated by the high viscosity of the resulting polymer solu
