ABSTRACT:
We disclose a monovinylarene/conjugated diene block copolymer, comprising: (i) a random (conjugated dienex/monovinylareney)mblock, wherein x is about 2.5 wt % to about 10 wt %, y is from about 90 wt % to about 97.5 wt %, and x+y is about 97.5 wt % to 100 wt %; and (ii) a (conjugated diene)nblock; wherein n is from about 20 wt % to about 30 wt %, m is from about 70 wt % to about 80 wt %, and m+n is from about 90 wt % to 100 wt %. We also disclose a method of forming the block copolymer and a method for fabricating an article from the block copolymer. The block copolymer typically exhibits a Tgat least about 10° C. less than the Tgof a reference polymer differing only in that x is about 0 wt % and y is about 100 wt %.
