A Miscible and Adaptive Poly(methyl acrylate)/Polystyrene Blend Formed by Multiple-Responsive Host-Guest Interactions

Polymer blends play a significant role in polymer science due to their new and unique properties compared with the individual polymer components. However, most polymer blends are immiscible and not adaptive to environmental stimuli. Here, an enhancement of the compatibility of an immiscible poly(methy acrylate)/polystyrene blend based on multiple-responsive benzo-21-crown-7/dialkylammoniumsalt host-guest interactions is made. Owing to the multi-responsiveness and reversibility of benzo-21-crown-7/dialkylammoniumsalt host-guest interactions, the polymer blend recovers its compatibility after being damaged by environmental factors, indicating its adaptiveness. image
