Functional in-chain silyl-hydride （Si-H） SBR copolymers of 4-vinyiphenyldimethylsilanol （VPDMS） and butadiene were synthesized by living anionic polymerization, in which active group Si-H was not lost and its content was controllable. Corresponding self-crosslinking elastomers were obtained by hydrosilation of Si-H group with vinyl bonds in chain. The copolymers and elastomers were characterized by 1a NMR, size exclusion chromatography （SEC）, Fourier transform infrared （FTIR） spectroscopy, differential scaskning calorimetry （DSC）, and thermogravimetry analysis （TGA） techniques.
