| titleOfInvention | Asymmetric star-shaped hydrogenated block copolymer and preparation method and application thereof |
| abstract | The invention discloses an asymmetric star hydrogenated block copolymer, a preparation method and application thereof. The structural formula of the asymmetric star-shaped hydrogenated block copolymer is as follows: (S) 1 EBS 2 )nM。S 1 Represents a polymer segment of a styrene monomer; s 2 Represents a polymer chain segment copolymerized by styrene and divinylbenzene monomers; and S 1 The molecular weight of the polymer chain segment is larger than S 2 A polymer segment; the polymer is mainly obtained by polymerization and coupling 1 BS 2 ) nM, followed by a hydrogenation step. The invention overcomes the technical problem of low coupling efficiency of styrene at the tail end of the polymer arm, prepares the sealing material with low compression deformation, high resilience and long service life, and is widely applied to the field of sealing parts. |
