“…It is astonishing that the mass production of plastics, which began in the 1950s, could potentially lead to 12 billion metric tons of plastic waste in the environment by 2050. 10 If wethe synthetic polymer communitydo nothing, the genuine triumphs of the last century of polymer science 184 may become mere monuments to our hubris. 185 We are calling on our community to help usher in the next century of sustainable polymer science.…”

Although Staudinger realized makromoleküles had enormous potential, he likely did not anticipate the consequences of their universal adoption. With 6.3 billion metric tons of plastic waste now contaminating our land, water, and air, we are facing an environmental and public health crisis. Synthetic polymer chemists can help create a more sustainable future, but are we on the right path to do so? Herein, a comprehensive literature survey reveals that there has been an increased focus on “sustainable polymers” in recent years, but most papers focus on biomass-derived feedstocks. In contrast, there is less focus on polymer end-of-life fates. Moving forward, we suggest an increased emphasis on chemical recycling, which sees value in plastic waste and promotes a closed-loop plastic economy. To help keep us on the path to sustainability, the synthetic polymer community should routinely seek the systems perspective offered by life cycle assessment.

“…314 As it is known, improvements are always necessary and usually derive from the applications side. 315 When the applications require polymers with very high molecular weights, extremely low dispersity, and exact design of the blocks in terms of composition (nanotechnology applications), anionic polymerization is still in the lead. It has also opened the way for the advent of controlled radical polymerization methods (ATRP, NMP, RAFT), which provided a resurgence in polymer synthesis over the last two decades.…”

Living anionic polymerization will soon celebrate 70 years of existence. This living polymerization is considered the mother of all living and controlled/living polymerizations since it paved the way for their discovery. It provides methodologies for synthesizing polymers with absolute control of the essential parameters that affect polymer properties, including molecular weight, molecular weight distribution, composition and microstructure, chain-end/in-chain functionality, and architecture. This precise control of living anionic polymerization generated tremendous fundamental and industrial research activities, developing numerous important commodity and specialty polymers. In this Perspective, we present the high importance of living anionic polymerization of vinyl monomers by providing some examples of its significant achievements, presenting its current status, giving several insights into where it is going (Quo Vadis) and what the future holds for this powerful synthetic method. Furthermore, we attempt to explore its advantages and disadvantages compared to controlled/living radical polymerizations, the main competitors of living carbanionic polymerization.

“…Block copolymers, their self-assembly and the self-assembled structures have been researched categorically in the last decades, exploring their vast potential in various fields [1][2][3][4][5][6][7][8][9][10]. One of the potential applications of block copolymers is in the fabrication of isoporous membranes, providing a high density of uniform functional pores (typically > 10 14 pores/m 2 ) on the top surface along with a tunable diameter and the perpendicular orientation above a macroporous asymmetric substructure support [11][12][13][14][15][16][17][18][19][20][21][22].…”

The conventional fabrication of isoporous membranes via the evaporation-induced self-assembly of block copolymers in combination with non-solvent induced phase separation (SNIPS) is achieved under certain environmental conditions. In this study, we report a modification in the conventional fabrication process of (isoporous) flat sheet membranes in which the self-assembly of block copolymers is achieved by providing controlled evaporation conditions using gas flow and the process is introduced as gSNIPS. This fabrication approach can not only trigger and control the microphase separation but also provides isoporous structure formation in a much broader range of solution concentrations and casting parameters, as compared to fabrication under ambient, uncontrolled conditions. We systematically investigated the structure formation of the fabrication of integral asymmetric isoporous membranes by gSNIPS. A quantitative correlation between the evaporation conditions (causing solvent evaporation and temperature drop) and the self-assembly of block copolymers beginning from the top layer up to a certain depth, orientation of pores in the top layer and the substructure morphology has been discussed empirically.
