Abstract
The present invention provides a medical device of a polymer composition. The composition has a first component obtained by copolymerizing a norbornene monomer and an ethylene monomer, the first component being in an amount from about 1-99% by weight of the composition; and a second component of an ethylene and α-olefin copolymer, the α-olefin having 6 carbons, the second component being in an amount from about 99% to about 1% by weight of the composition.
