Patent ID: 8071681

Claim:
A polymeric composition comprising: (i) from about 25 wt. % to about 65 wt. %, based on the total weight of the polymeric composition, of a polymer comprising at least 75 wt. % propylene-derived units and having a heat of fusion of less than 75 J/g and an isotactic triad fraction of from about 65% to about 99%; (ii) from about 16 wt. % to about 50 wt. %, based on the total weight of the polymeric composition, of a styrenic block copolymer (SBC), wherein the SBC is selected from the group consisting of styrene-butadiene-styrene, styrene-ethylene/butylene-styrene, styrene-ethylene/propylene-styrene, styrene-isoprene-styrene, and mixtures thereof, and wherein the SBC is comprised of less than 20 wt % diblock segments and has a styrene content of about 10 to about 50 wt %, and the SBC has an MFR (230Â° C./5 kg) within the range of from about 0.1 to about 40 dg/min; (iii) from about 10 wt % to about 36 wt. % of a propylene homopolymer or copolymer having an upper limit of 8 wt % of copolymer units selected from ethylene and C 4 -C 12 alpha-olefins; and wherein the polymeric composition has a tension set from 200% elongation of less than 50% at 23Â° C. and wherein the weight percentages of polymer are additive to 100.0%.
