Polymer branching
Polymer architecture in polymer science relates to the way branching leads to a deviation from a strictly linear polymer chain. Branching may occur randomly or reactions may be designed so that specific architectures are targeted. It is an important microstructural feature. A polymer's architecture affects many of its physical properties including solution viscosity, melt viscosity, solubility in vari… WebApr 6, 2024 · Long branches are found to have comb-like or we can say star-shaped structures. - let’s see an example of this: - Let’s discuss about Linear polymer: - In linear …
