| titleOfInvention | Coupling agent and star-line blended conjugated diene polymer and preparation method and application thereof |
| abstract | The invention relates to the field of anionic polymerization, and discloses a coupling agent and star-line blended conjugated diene polymer, and a preparation method and application thereof. The coupling agent comprises one of the compounds with the structure shown in the formula (I) and one of the compounds with the structure shown in the formula (II), wherein in the formula (I) and the formula (II), each R is independently C 1 ‑C 4 Alkyl, substituted or unsubstituted C 3 ‑C 6 Cycloalkyl or substituted or unsubstituted phenyl; y is halogen; a is 1 and b is 3; c is 2-3, d is 1-2, and c + d is 4; m is Si or Sn; wherein, substituted C 3 ‑C 6 The substituent in the cycloalkyl and substituted phenyl is C 1 ‑C 3 An alkyl group. The star-blending conjugated diene polymer obtained by the preparation method of the star-blending conjugated diene polymer using the coupling agent has trimodal molecular weight distribution and wider molecular weight distribution, so that the processing performance of the star-blending conjugated diene polymer is more excellent. R a MY b Formula (I) R c MY d Formula (II). |
