The biannual Emerging Investigator themed issue of Polymer Chemistry has become a tradition by now and I am very pleased that once again we have assembled a cross-section of the most exciting research going on in young laboratories.

Bridging the gender gap in the sciences and empowering female researchers is of critical importance for the diversity and well-being of our field. I noted in the editorial of the 2018 Emerging Investigators themed issue that the number of submissions we received from young female group leaders was not satisfactory and I promised to actively work on this year's issues to address the matter. I am very pleased to report that at the time of publication a third of all articles published in the current themed issue are from female group leaders, which is perhaps close to the true fraction of laboratories led by female colleagues. It is upon all of us to be role models for the next generation of scientists and to show that career paths in science are irrespective of gender or gender orientation. We as publishers can only reflect what is happening at universities throughout the world, but I am positive we are finally on a good road to gender equity in the sciences, although there is certainly no room for complacency. To read the latest Royal Society of Chemistry report on gender bias in publishing visit https://rsc.li/genderbias.

The themes explored in the current themed issue are as diverse as the backgrounds of our authors. With around 50 contributions in the current issue, I cannot highlight every single one in the current editorial, thus the below represents my editor's pick of what I find – subjectively – most interesting and particularly noteworthy.

With sustainability and waste limitation a central theme in today's world, Fiona Hatton contributes a very timely review on the polymerization of monomers from renewable resources focused on RAFT polymerization, which provides an easy access point for all polymer chemists considering basing their soft materials on renewable feedstock (DOI: 10.1039/C9PY01128E). Staying with the theme of chain transfer reactions, Will Gutekunst introduces an avenue to prepare an array of functional polymer chains based on a single Grubbs initiator and an efficient and fast transfer process (DOI: 10.1039/C9PY00965E). Reversible Deactivation Radical Polymerizations (RDRPs) continue to be exploited for the construction of therapeutic delivery vectors and a particularly interesting example comes from the team of Efrosyni Themistou, which prepares star polymers via RAFT chemistry, featuring an acid degradable core, enabling the intracellular delivery of DNA (DOI: 10.1039/C9PY00573K). PEGylated polymers play a critical role in the pharmaceutical field and the synthesis of PEGylated block copolymers is a particularly challenging endeavour. Xiaoling Liu exploits Cu-mediated SET polymerization in an aqueous environment to achieve well-defined block copolymers, while obtaining a precise picture of the underpinning kinetics that guide the chain extension experiments (DOI: 10.1039/C9PY01202H).

While polymer scientists often associate sulfur chemistry with the RAFT process, Hatice Mutlu and her team teach us that elemental sulfur can be a versatile starting material for the synthesis of bio-based polyesters, providing a fresh look at the usefulness of this element in our field (DOI: 10.1039/C9PY01152H).

While RDRP processes are perhaps still the most popular systems for the facile design of a virtually limitless array of polymer architectures, Bret Fors and colleagues remind us that long established polymerization methods such as anionic polymerizations still have a few tricks up their sleeves: based on a highly accurate kinetic model, the team shows just how well the molecular weight distributions of anionically prepared polymers can be predicted (DOI: 10.1039/C9PY00074G).

On the single chain level, Yoan Simon and his team show that learning from nature pays off for the photochemically driven construction of single chain nanoparticles, which are discussed as potential biomimetic catalysts in the current literature (DOI: 10.1039/C9PY01235D). The team makes clever use of disparate monomers that impart specific solvencies onto the polymer chains.

The science showcased herein shows that the future of our field is in the best of hands and I hope that all established research leaders – irrespective of gender – will not only mentor but actively sponsor our next-generation scientists, by providing opportunities to them for presenting and publishing. It is time for a generational change in the seemingly ever-identical line-up of invited and plenary speakers at conferences, sadly still dominated by male scientists. If the current themed issue serves as inspiration to conference chairs and university promotion committees as to where our future lies, we will have achieved one of our aims not only at Polymer Chemistry, but also at the Royal Society of Chemistry.

I hope you enjoy the current themed issue as much as I do.
