Abstract

A composition includes a blend of (a) a multi-block copolymer including at least one block of an elastomeric polymer and at least one block of a first polymer including a chiral polymer having a stereo isomeric configuration; and (b) a second polymer including an anti-chiral polymer corresponding to the chiral polymer in (a), wherein the second polymer includes an opposite handed stereo isomeric configuration to the chiral polymer in (a); wherein the blend of the chiral polymer and the anti-chiral polymer form stereo complex sites. A flexible tubing material further includes the blend. In an embodiment, a method of making the blend material is also provided.
