WebWithout the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. Ethers do have nonbonding electron pairs on their oxygen atoms, however, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. Webnumber of hydrophilic groups such as hydroxyl (–OH) and carboxyl (–COOH) on the SA structure,18 and partly because SA contains a large number of –OH, which constitutes a dynamic non-covalent bond within the hydrogel.19 Frontal polymerization (FP) is a simple and rapid method of converting monomers into polymers.
