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. WebAlkenes can be used to make polymers. Polymers are very large molecules made when many smaller, reactive molecules join together, end to end. The smaller molecules are …
