Introduction
The polymer (or copolymer) elastomer, based on styrene and butadiene as monomers and prepared in the process of solution polymerization, is usually named SSBR. The proprietary SSBR technology developed by Sinopec is an integrated commercial technology with organic lithium compounds as initiators and low carbon aliphatic hydrocarbon as solvent. The key structure parameters of the macromolecule can be adjusted by anionic living polymerization processes for preparing a series of SSBR grades with different properties.
SSBR can be widely used in many fields such as the automobile tyre industry. The automobile tyre made of SSBR has high strength, low heat effect in compression, especially the excellent wet skid resistance and low rolling resistance. These properties of the tyre surely are beneficial to reinforcing traffic security of the automobiles and reducing fuel consumption, and therefore are suitable to the rapid development of high way. SSBR also has the characteristics of good colour acceptance and low shrinkage rate, so the shoes made of SSBR usually possess clear tread pattern, brilliant colour and comfortable feeling. In addition, SSBR has entered many other application fields of synthetic rubbers, and has been manufactured into different industries such as tubes, plates and tapes, vibration-absorptive material, insulator and foamable material. In modifying bitumen and plastics, SSBR has already shared a great portion of the domestic market.
