摘要

无金属阳离子聚合可制备无残余金属污染的聚合物，从而无需额外的净化处理。在这里，使用有机碘作为引发剂前体，开发了一种无金属的异丁基乙烯基醚（IBVE）光引发聚合法。成功获得了分子量可控、分子量分布窄（Đ <1.10）的 PIBVE。聚合动力学显示了反应的可控性，并证明了原位链延伸。此外，我们还引入了一种潜伏引发剂策略，可通过调节光源来控制引发剂的生成过程，并为调整所获得聚合物的分子量分布提供了一种简便的方法。

Metal-Free Photoinitiated, Controlled Cationic Polymerization of Vinyl Ethers Using Organic Iodides

Metal-free cationic polymerization enables the preparation of polymers without residual metal contamination, eliminating the need for additional purification. Here, a metal-free photoinitiating polymerization of isobutyl vinyl ether (IBVE) was developed using organic iodide as the initiator precursor. PIBVE with controlled molecular weight and narrow molecular weight distribution (Đ < 1.10) was successfully obtained. The polymerization kinetics demonstrated a controlled reaction, and in situ chain extension was demonstrated. In addition, we introduced a latent initiator strategy, allowing to control the generation process of the initiator through adjustment of the light source and providing a facile way to tune the MWD of the obtained polymer.
