Abstract:
Microst ructure and sequence dist ribut ion of SSBR w ere studied w ith 13 C-NMR. Ef fects of microstructure and sequence dist ribut ion of SBR on the physical properties, thermoxgen and abrasion of SSBR vulcanizates were discussed. It w as found that microstructure of SBR had very important inf luence on cure properties and physical propert ies of SBR compounds. The more the content s of cis-in st ructure, the faster the cure velocity. The more the contents of trans-in st ructure, the hig her the tensile strength. The more the content s of styrene in st ructure, the more hysteresis loss and the bet ter abrasive resistance.
