ABSTRACT:
Polymer blends of non-crystalline mesomorphous polypropylene and a polymer compatible with such polypropylene and the method of making such polymer blends are provided. Such compatible polymer blends exhibit substantial maintenance of structural integrity after exposure to gamma irradiation and provide heat sealing properties, puncture resistance, and tear strength. Films, fibers, and other articles made from such blends may be used in various applications, including medical articles such as medical packaging films, ostomy pouches, and transdermal delivery patches, which may require sterilized storage prior to usage.
