Lots of SEC samples ready to be shipped. It took some time to find the capacity to work on it, but now our @iupacpolymer.bsky.social project on SEC accuracy is taking final shape!

Front cover

Issue 34 of @polymerchem.rsc.org features a cover by Maniar and Martins Lacerda et al. with semi-rigid biobased polyesters from renewable resources. Also inside-materials for CO₂ separation and a superabsorbent hydrogel removing heavy metals. pubs.rsc.org/en/content/a...

Reconsidering terms for mechanisms of polymer growth: the “step-growth” and “chain-growth” dilemma The terms “step-growth polymerization” and “chain-growth polymerization” are used widely in both written and oral communications to describe the two main mechanisms of polymer growth. As members of th...

This all started with a dilemma over how classic terms "step-growth" and "chain-growth" can be confusing. This article in @polymerchem.rsc.org kicked off the discussion to find better terms: pubs.rsc.org/en/content/a...
