To obtain a novel resin‐reinforced elastomer, a butadiene rubber composite filled with syndiotactic polybutadiene (SPB) resin [vinyl cis rubber (VCR)] is designed. The VCR is synthesized by two‐step polymerization of 1,3‐butadiene in one pot. The SPB fibril is highly dispersed in a 1,4‐cis polybutadiene rubber (BR) matrix. Increasing the SPB content improves the tensile strength of the VCR. The nanostructure of the VCR is investigated by using a nano‐palpation atomic force microscope. The interfacial region between BR and SPB is detected with an intermediate Young's modulus. In addition, the average Young's modulus of the region combined with the matrix and interfacial shows a good correlation with the Young's modulus obtained from a tensile test. The interfacial region should be one of the key structures to consider the reinforcement mechanism in VCR. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019 , 136 , 47934.
