| titleOfInvention | SBS containing 1,2 structure uniformly distributed butadiene block and hydride thereof, preparation and application method |
| abstract | The invention discloses SBS containing 1,2 structure uniformly distributed butadiene block and hydride SEBS and preparation and application methods thereof, wherein the preparation process of SBS is that styrene is initiated by initiator under the action of activator for first-stage polymerization, the second-stage polymerization process is that 1,2 structure regulator is dissolved in butadiene and uniformly added into a polymerization kettle within 16-18 min, after the addition is finished, the reaction is carried out for 8-12 min, the third-stage polymerization can be carried out by polymerizing styrene or coupling by adopting a coupling agent, the content of 1, 2-addition unit in polybutadiene block in the obtained SBS is 38-42% and uniformly distributed, the obtained SEBS after hydrogenation is good in compatibility and stability with naphthenic oil or white oil, the oil product is low in migration rate in SEBS, high in light transmittance and capable of being widely applied to transparent elastic materials. |
