Temperature‐sensitive hydrogel microspheres formed by liquid–liquid phase transitions of aqueous solutions of poly(N,N‐dimethylacrylamide‐co‐allyl methacrylate)

Abstract Poly( N , N ‐dimethylacrylamide‐ co ‐allyl methacrylate) (DMA‐ co ‐AMA) copolymers were prepared by the copolymerization of N , N ‐dimethylacrylamide with allyl methacrylate (AMA). The methacryloyl group of AMA reacted preferentially, and this resulted in pendant allyl groups along the copolymer chains. Aqueous solutions of these DMA‐ co ‐AMA copolymers were thermoresponsive and showed liquid–liquid phase transitions at temperatures …
