Highly pH and Temperature Responsive Microgels Functionalized with Vinylacetic Acid
Abstract
Temperature-responsive microgels based on poly(N-isopropylacrylamide) (PNIPAM) and functionalized with vinylacetic acid (VAA) are observed to exhibit a host of novel swelling responses compared with equally functionalized microgels prepared using the conventional acrylic acid (AA) and methacrylic acid (MAA) comonomers. VAA−NIPAM microgels are ionized over a narrow pH range and show functional group pK a values which are independent of the …
