| titleOfInvention | Conjugated diene and monovinylarene random copolymer and preparation method thereof |
| abstract | The invention relates to the field of conjugated diene and monovinylarene random copolymers, and discloses a conjugated diene and monovinylarene random copolymer and a preparation method thereof. The method is to carry out a continuous copolymerization reaction in a single reactor, and the method comprises: under anionic polymerization conditions, a first part of a conjugated diene, a monovinyl arene, a solvent, a gel inhibitor and a single organolithium are initiated to initiate The reaction material of the agent is continuously introduced from the bottom of the reaction kettle, the second part of the conjugated diene is continuously introduced into the middle of the reaction kettle, and the third part of the conjugated diene is continuously introduced into the upper part of the reaction kettle, and The polymerization temperature was controlled at 90-140°C. Through the method of the present invention, without adding any structure regulator or random agent, and under the conditions of relatively high reaction temperature and reasonable residence time, a conjugate with controllable basic molecular weight and low vinyl content can be prepared Random copolymers of dienes and monovinylarenes. |
