Abstract
The specification discloses a method for making DCPD based resins that have essentially unimodal molecular weight distributions. The method comprises polymerizing dicyclopentadiene monomer in the presence of an organic sulfur compound which is effective to control the molecular weight distribution of the polymerized product. For end-use performance in inks, adhesives, coatings and other related areas, the invention provides dicyclopentadiene based resins having molecular weight distributions which effectively enhance the resin solubility and compatability in various formulations.
