摘要： PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer having improved workability. SOLUTION: A rubber of a mixture composed of a thermoplastic resin and a working property, are dynamically vulcanized to form a thermoplastic elastomer, wherein a content of the thermoplastic resin is about 10-about 80 wt.% based on a total weight of a combined rubber and thermoplastic resin, and wherein the content of the working additive is about 1-about 25 wt.% based on the total weight of the combined vulcanized rubber and thermoplastic resin. The working additive that is a polymer, is a linear polyolefin resin having a melt flow of about 1,000 dg/min or above, a diene-reformed polyolefin polymer having a melt flow of about 1,000 dg/min, a diene-derived polymer unit of about 0.005-about 2.00 mol% and a viscosity-average branching index of about 0.4-about 0.95, or a mixture of the above linear polyolefin resin and the above diene-reformed polyolefin polymer. A vulcanized rubber having a croslinking density of about 40-about 180 mol% per rubber of 1 ml, is obtained by dynamically vulcanizing the rubber.
