WebMay 22, 2014 · Miscible polymer blends featuring strong hydrogen bonding interactions are of interest to materials scientists, because they can exhibit improved or modified properties relative to those of their individual constituent polymers [1,2,3].The strength and extent of hydrogen bonding in copolymer or polymer blends depend on the respective affinities … WebPolymer molecules are joined by covalent bonds that are specific to each type of polymer which we will discuss in further detail later. On the other hand, the covalent bonds that link polymers can be broken down by adding water through a process called hydrolysis (Fig. 2).
A polymer is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fun… WebPolymers are created by the process of polymerization, wherein their constituent elements, called monomers, are reacted together to form polymer chains, i.e., 3-dimensional networks forming the polymer bonds. …
