Thermoplastic composition

   
   

The subject invention discloses a thermoplastic composition which is comprised of a blend of a thermoplastic polyolefin resin and a modified elastomer, wherein said thermoplastic polyolefin resin selected at least from the group of polyethylene, isotactic polypropylene, syndiotactic polypropylene, polypropylene impact copolymers containing about 1-7% by weight of ethylene, butene, hexene, or octene, polyolefin copolymers such as ethylene-butene, hexene, or octene, polybutene, reactor grade modified polypropylene, metallocene polypropylene, oxypolypropylene, wherein said modified elastomer is comprised of a conjugated diene selected from 1,3-butadiene and isoprene, wherein said modified elastomer is highly branched, wherein said modified elastomer is characterized by having a G' and G" frequency crossover of no more than 4 radians/s at 100.degree. C., wherein the thermoplastic polyolefin is present in an amount which is within the range of about 5 parts by weight to about 95 parts by weight, and wherein the modified elastomer is present in an amount which is within the range of 5 parts by weight to about 95 parts by weight, based upon the total weight of the thermoplastic composition.
