Abstract:
A styrenic monomer-diolefin copolymer comprises polystyrenic monomer micro-blocks and polydiolefin micro-blocks, in which the content of styrenic monomer units is 10-80 wt %, the ratio of diolefin units of 1,2-structure is less than 30% in the total diolefin units, and the number-average molecular weight (Mn) of the copolymer is 25,000-500,000. The preparation methods and uses in foam products thereof are also disclosed.
