QUESTION 6 10 points Polystyrene (PS) is a typical thermoplastic polymer and polybutadiene (PB) is a typical elastomer. PS and PB is not miscible each other, thus forming polymer alloy system of PS and PB is difficult. However, PS and PB can from copolymer, such as SBR (Styrene-Butadiene random copolymer) and SBS (Styrene-Butadiene-Styrene tri-block copolymer). One can be used for asphalt coating and the other can be used as shoe sole, although both may show excellent viscoelastic behaviors. Explain your choice of which one is better to be used for asphalt coating and which one as shoe sole and show your reason why with more than 100 words.
