Abstract
A blend composition including from about 1 to about 99 weight percent syndiotactic polypropylene (sPP) and from about 99 to about 1 weight percent styrene-butadiene-styrene block copolymer (SBS) and olefin elastomer, based on the weight of the sPP, SBS and olefin elastomer. A method of making the composition includes contacting the sPP, SBS and olefin elastomer at a temperature above the melting point of the sPP and olefin elastomer, with useful articles formed therefrom.
