Abstract
The present disclosure relates to a rubber composition and a method of preparing the same, the rubber composition comprising a viscosity modifier and a modified polymer having a structure in which a molecular weight regulator is coupled to at least one of both ends of an at least partially hydrogenated or non-hydrogenated petroleum resin. The rubber composition according to the present disclosure has improved processability and thus may replace process oil, and may markedly improve gas impermeability.
Claims11
A resin composition comprising a modified polymer having a structure in which a molecular weight regulator is coupled to at least one of both ends of an at least partially hydrogenated or non-hydrogenated petroleum resin,
- wherein the resin composition further comprises a viscosity controller, and
- wherein the viscosity controller is a low-viscosity liquid resin having a viscosity (25° C.) of 20-500 cps, and
- wherein the low-viscosity liquid resin is selected from hydrogenated DCPD-C9 copolymer resins, hydrogenated DCPD resins, and mixtures thereof.
