Beschreibung
Zusammenfassung:	The polymerized rosin compound of the invention includes a rosin dimer component (A) including a bifunctional rosin dimer component (a1) represented by formula (1): ROOC-X-COOR, wherein X represents a rosin dimer residue, and R represents hydrogen, an alkyl group of 1 to 5 carbon atoms, or a benzyl group, wherein the rosin dimer component (A) contains a content of the bifunctional rosin dimer component (a1) of 80% by weight or more and the polymerized rosin compound contains a content of the rosin dimer component (A) of 80% by weight or more. The polymerized rosin compound contains a large amount of the bifunctional rosin dimer component and makes it possible to obtain linear polymer with a high molecular weight.
