| titleOfInvention | Low cis-polybutadiene rubber and preparation method thereof, and HIPS resin and preparation method thereof |
| abstract | The invention relates to the field of synthetic rubber and modified resin thereof, in particular to low cis-polybutadiene rubber and a preparation method thereof, and HIPS resin and a preparation method thereof. The molecular weight of the low-cis polybutadiene rubber is trimodal distribution, the number average molecular weight of a first peak is 125,000-; wherein the peak area of the number average molecular weight of the first peak is 40-79%, the peak area of the number average molecular weight of the second peak is 20-60%, and the peak area of the number average molecular weight of the third peak is 1-10%. The low cis-polybutadiene rubber provided by the invention has a trimodal molecular weight, has a proper vinyl content and a proper solution viscosity, can be used as a toughening agent in HIPS resin synthesis, and the obtained HIPS resin has higher glossiness and impact resistance. |
