Since chain transfer preferentially occurs with large molecules, a branched molecule becomes more branched (ref.
Because generating the branched structure dominates over molecular weight distribution, the degree of branching and gel-content are the most important structural variables.
the researchers also are investigating more highly branched cores.
They recently reported making dendritic molecules with a branched structure consisting of 2.687 carbon atoms, 2,304 hydrogen atoms and 381 oxygen atoms -- always bound into the same arrangement.
For the most part, however, the star branched
polymers exhibit the green strength benefits normally attributed to high viscosity polymers while maintaining the fast stress relaxation characteristics associated with low viscosity polymers.
