We investigate the use of in situ enzyme degassing to facilitate the open-to-air reversible addition–fragmentation chain transfer (RAFT) polymerization of hydroxyethyl acrylate (HEA) in a wide range of complex aqueous solvents, including, beer, wine, liquor, and fermentation broth. This enzyme-assisted polymerization procedure is impressively robust, and poly(HEA) was attained with good control over molecular weight and a narrow dispersity in nearly all of the solvents tested. Kinetics experiments on HEA polymerization in whisky and spectroscopic analysis of the purified polymers suggest high end-group fidelity, as does the successful chain extension of a poly(HEA) macro chain transfer agent with narrow dispersity. These results suggest enzyme-assisted RAFT may be a powerful and underutilized tool for high-throughput screening and materials discovery and may simplify the synthesis of well-defined polymers in complex conditions.

复杂溶剂中的露天 RAFT 聚合：从威士忌到发酵液

我们研究了使用原位酶脱气来促进丙烯酸羟乙酯 (HEA) 在各种复杂的水性溶剂（包括啤酒、葡萄酒、白酒、和发酵液。这种酶辅助聚合过程令人印象深刻，并且在几乎所有测试的溶剂中均能很好地控制分子量和窄分散性，从而获得了聚 (HEA)。威士忌中 HEA 聚合的动力学实验和纯化聚合物的光谱分析表明端基保真度很高，具有窄分散性的聚 (HEA) 大链转移剂的成功扩链也是如此。
