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 fundamental to biological structure and function. Polymers, both natural and synthetic, are cr…

Web24.1: Introduction. 24.3: Anionic Polymerization of Epoxides. Polymers are long chain giant organic molecules are assembled from many smaller molecules called monomers. Polymers consist of many repeating monomer units in long chains. A polymer is analogous to a necklace made from many small beads (monomers). Many monomers are alkenes or … Web4- Polymers are at the other end of the spectrum. They have moduli that are low, roughly 50 times less than those of metals, but they can be strong—nearly as strong as metals. A consequence of this is that elastic deflections can be large. They creep, even at room temperature, meaning that a polymer component under
WebSolid-state polymerization is one of the well-established topics in the field of polymer science explored in the 1960s. The development of solid-state polymerization was largely due to the use of high energy radiation, such as γ-rays, X-rays, electron beams and sometimes α particles, by polymer chemists.

WebNon-ionic polymer gel, swollen with dielectric solvent, can be extremely deformed as is the case for non-ionic polymer plasticised with non-ionic plasticiser. Instead of the ‘charge-injected solvent drag’ as a mechanism of the gel actuation, the principle is based on local asymmetrical charge distribution at the surface of the gel 18 .
