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. WebFlexible chains show relatively low Tg than rigid chains. Aliphatic C-C, C-O bonds, and Si-O-Si backbone show low Tg. When ring structures introduce to the polymer backbone, the …
