## Abstract A starโshape styreneโbutadieneโstyrene triblock copolymer SBS (802) was synthesized and fractionated into four fractions coded as 802โF1 (four arms), 802โF2 (two arms), 802โF3 (one arm), and 802โF4 by repeating fractional precipitation. Their weightโaverage molecular weight (__M__~w~) w
## Abstract Symmetric linear Sโ(S/B)โS triblock copolymers with 80 wt.โ% of PS having a block composition of 20โ60โ20 and a S/B ratio of 70:30 in the middle block are studied with varying molecular weights ($\overline M \_{\rm w}$). Increase in the $\overline M \_{\rm w}$ leads to a change in the m
