PROBLEM TO BE SOLVED: To provide an aliphatic-alicyclic copolymer petroleum resin composition having excellent preservation stability, especially the one hardly forming a gel-shaped material and causing little change of resin properties with time at the preservation, and to provide a method for producing the resin composition. SOLUTION: The aliphatic-alicyclic copolymer petroleum resin composition contains 0.05-2 pts.wt. hindered amine compound based on 100 pts.wt. aliphatic-alicyclic copolymer petroleum resin having≤13% olefinic double bond-hydrogen area rate in a proton NMR spectrum. The method for producing the resin composition is also provided. COPYRIGHT: (C)2010,JPO&INPIT |
