Provided are a polymer composition having the properties of natural rubber (durability (anti-fracture properties, abrasion resistance and anti-crack-growth properties), and a manufacturing method for same. A manufacturing method for a polymer composition containing a mixture of polyisoprene and polystyrene or polybutadiene, wherein styrene monomers or butadiene monomers are polymerized in the presence of a catalyst, thus synthesizing polystyrene or polybutadiene, and then isoprene monomers are added, thus synthesizing polyisoprene, and thus the mixture is generated. The amount of styrene monomers or butadiene monomers is 10 mol% or less of the total amount of the styrene monomers or butadiene monomers and the isoprene monomers. |
