Abstract
The present invention relates to a resin composition comprising: a base resin comprising a petroleum resin of which at least a part is hydrogenated or non-hydrogenated; and an additive comprising a modified C9 polymer having a structure in which a molecular weight modifier binds to at least one terminal of the two terminals of the petroleum resin of which at least a part is hydrogenated or non-hydrogenated. The present invention also relates to a gas barrier film comprising the resin composition, and a tire.
Claims27
A resin composition comprising:
- a base resin comprising a non-hydrogenated or at least partially hydrogenated petroleum resin;
- and an additive comprising a modified petroleum resin having a structure in which a molecular weight modifier is bonded to at least one end of the two ends of the non-hydrogenated or at least partially hydrogenated petroleum resin.
A method of preparing a resin composition, comprising:
- obtaining a semi-solid resin by blending, at a temperature of 100° C. to 180° C., a base resin comprising a non-hydrogenated or at least partially hydrogenated petroleum resin;
- and an additive comprising a modified petroleum resin having a structure in which a molecular weight modifier is bonded to at least one end of the two ends of a non-hydrogenated or at least partially hydrogenated petroleum resin.
