CRP relies on a reversible … WebJan 1, 2014 · Structures of end groups of a polymer chain are usually not specified because they have little effect on bulk properties of the polymer and often they are not known. This statement fails in the case of certain macromolecules such as hyper-branched polymers for which the properties may be critically dependent on end groups.
