Abstract

Embodiments of the invention provide block composites comprising a soft copolymer, a hard polymer and a block copolymer having a soft segment and a hard segment, wherein the hard segment of the block copolymer is the same composition as the hard polymer in the block composite and the soft segment of the block copolymer is the same composition as the soft copolymer of the block composite and their use as impact modifiers.
