WebMay 17, 2024 · Polymers are extremely large molecules composed of long chains, much like paper clips that are linked together to make a long strand. The individual subunits, which can range from as few as 50 to more than 20,000, are called monomers (from the Greek mono meaning one and meros meaning part). 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

WebThe properties of the polymer, such as permeability of the polymer structure, have also a key role. The size of the gaps in the polymer depends largely on the physical state, which can be either glassy, rubbery or crystalline. For example rubbery polymers have larger gaps and therefore higher diffusion rates compared to other types of polymers.
