摘要： Elastic materials, particularly films, strips, coatings, ribbons and sheets made from at least one substantially linear ethylene polymer are disclosed which can be fabricated on conventional polyolefin extrusion equipment. They can be used to produce elastic composite structures that are stretchable and have recycle compatibility between elastic and non-elastic components. The novel materials have at least about 80% recovery at 100% strain and are especially useful in making fabricated composite articles (e.g., disposable diapers).
