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.
Claims25
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.
(canceled)
A method for preparing a resin composition, the method comprising obtaining a polymerization reaction product by performing a polymerization reaction by adding a polymerization catalyst or/and heat to a solution comprising one or more monomers derived from C5 fractions, one or more monomers derived from C9 fractions, one or more monomers selected from a cyclic diolefin monomer and a linear olefin monomer, and a molecular weight regulator.
