SOFT MATERIALS APPLICATIONS STRUCTURE VS. PROPERTIES

As you might expect, the influence of the nature and density of side groups vs. the backbone structure will strongly depend on the relative composition of each polymer unit, as well as how open the structure is to its environment. Regarding the relative composition of a polymer, even though a polymer may have a polar backbone structure (e.g., ether and/or ester linkages), the structure may not be soluble within polar solvents. That is, if long nonpolar side chains are also present in the polymeric 

and polysulfone, tend to form amorphous polymers. Based on their disordered structure, amorphous polymers have low shrinkage, a transparent appearance, a broad melting point, and poor chemical and wear resistance.
