Beschreibung
Zusammenfassung:	PURPOSE: A reformed sulfur polymer is provided to have excellent long-term storage properties and workability together with excellent mechanical strength like compressive strength, bending strength, etc. CONSTITUTION: A reformed sulfur polymer is synthesized by polymerization of 100.0 parts by weight of sulfur, and 1-10 parts by weight of dicyclopentadiene, 0.05-3 parts by weight of C8-75 aryl compound containing a functional group in chemical formula 1-a, or a compound in chemical formula 1: S(R3COOR4)2. In chemical formula 1-a, R1 and R2 is same or different, and is respectively C1-18 alkyl group. In chemical formula 1, R3 is -(CH2)x-, x is an integer from 0-4, and R4 is C1-20 alkyl group.
