Constitutional repeating unit of connectivity \(c \ge 4\) connected to more than two but less than \(c\) other constitutional repeating units.
Example of a hyperbranched macromolecule part with a semi-dendritic constitutional repeating unit of connectivity \(c = 4\) (circled), connected to three other constitutional repeating units and to one hydroxymethyl end-group. The preferred constitutional repeating unit is chosen such that the branch points are at its end in the dendron direction.
