The effects of the styrene-butadiene (SB) diblock copolymer on the viscoelastic properties of styrene-butadiene-styrene (SBS) triblock copolymers were examined in both in the neat state and within specific product applications. The addition of the SB diblock copolymer into a pure SBS triblock copoly

## Abstract The morphology and mechanical properties of blends of isotactic polypropylene (i‐PP) and a maleated butadiene–styrene–butadiene triblock copolymer with maleic anhydride (SBS–MAH), i‐PP/SBS–MAH, were investigated and compared with those of corresponding blends of i‐PP and a styrene–butad
## Abstract A star‐shape styrene–butadiene–styrene triblock copolymer SBS (802) was synthesized and fractionated into four fractions coded as 802‐F1 (four arms), 802‐F2 (two arms), 802‐F3 (one arm), and 802‐F4 by repeating fractional precipitation. Their weight‐average molecular weight (__M__~w~) w
