| titleOfInvention | Random copolymer and random copolymer composition, use thereof and anionic polymerization process |
| abstract | The invention discloses a random copolymer and a random copolymer composition, application thereof and an anionic polymerization method, wherein the method comprises the following steps: (1) under the condition of anionic polymerization, in the presence of a polar additive, contacting a polymerization monomer with an organic lithium initiator in a solvent, wherein the polymerization monomer contains conjugated diene and monovinyl aromatic hydrocarbon; (2) optionally, contacting the mixture obtained by the step (1) with a coupling agent under the coupling reaction condition, wherein the polar additive is selected from compounds shown in a formula II. According to the anionic polymerization process of the present invention, a monovinylarene-conjugated diene random copolymer (composition) having both a lower pendant group content and a lower monovinylarene block content can be prepared by employing a polar additive having a specific structure. |
