| titleOfInvention | Block copolymer, block copolymer composition, vulcanized rubber, application of block copolymer, block copolymer composition and vulcanized rubber and block copolymer preparation method |
| abstract | The invention discloses a copolymer and a copolymer preparation method. Structural units in the copolymer are connected in a PB1-SB-PB2 mode, wherein the PB1 block is a block formed by conjugated diene; the SB block is a random copolymerization block formed by conjugated diene and monovinylarene; the PB2 block is a block formed by conjugated diene; and by taking gross of the copolymer as reference, the content of vinyl as a lateral group in the PB1 block is 2-6.5% by weight, the content of vinyl as a lateral group in the SB block is 9-55% by weight, and the content of vinyl as a lateral group in the PB2 block is 1-3.5% by weight. The invention also discloses a composition formed by coupling of the copolymer and vulcanized rubber formed by the copolymer. A material formed by the copolymer, particularly when the copolymer is styrene-butadiene copolymer, has relatively good damping performance within a wider temperature range, and meanwhile, has better mechanical property. |
