1. A multiblock copolymer comprising:
a block obtained from a polyester having an average MN of from about 2,000 to about 200,000, wherein the polyester contains one or more terephthalate units; and
a block obtained from a polyolefin having an average MN of from about 2,000 to about 200,000, wherein the polyolefin is selected from the group consisting of polyethylenes, polypropylenes, polystyrenes, alkyl polystyrenes, polybutylenes, polybutadienes, polyacrylates, polymethacrylates, polyisoprenes, polyisobutylene, polyvinylidene dichloride, polyethylene vinyl alcohol, and combinations thereof.
