WebMay 18, 2024 · Branched — Sometimes, a polymer chain can have segments branching off of the main carbon backbone. This structure is called a branched polymer chain. As you might expect, the branches prevent the polymer chains from packing closely together, though the branches themselves never fully connect one chain to another. WebA key property that we are interested in when discussing a polymer chain is the size of the polymer. The size of a polymer is rarely equivalent to the sum of the lengths of all of its monomers since the exibility of the polymer backbone (and entropy!) causes them to coil up.
