Title:
HYDROGENATED STYRENE BLOCK COPOLYMER AND PREPARATION METHOD THEREFOR AS WELL AS USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2016/127355
Kind Code:
A1
Abstract:
A block copolymer, having a structural formula of S1
p-D-S2
q(I), wherein S1 and S2 are independently styrene monomer polymerization blocks, and the weights of S1 and S2 respectively account for 8.0-20.0% of the total weight of the block copolymer; D is a polymerization block of a styrene monomer and a conjugated diene monomer; p and q are respectively 0 and 1 but cannot be simultaneously 0; styrene monomer units in S1,S2 and D can be identical or different; the dynamic mechanical performance of a block copolymer thermoplastic elastomer is determined by means of dynamic mechanical thermal analysis, the block copolymer thermoplastic elastomer has an internal friction peak (tanδ) at -30-35 °C when the frequency is 1Hz constantly and the heating rate is 3 K/min, the peak value of the internal friction peak is -5-10 °C, and the peak value tanδ ≥ 0.7. Also provided are a preparation method for the block copolymer and a use of the block copolymer.
