| 摘要 |
<p>The present invention relates to a method of making improved polyolefinic elastic articles from cured, irradiated or cross-linked amorphous ethylene interpolymers. In particular, the invention relates to a method of making a shaped article (for example, film or fiber) characterized by improved elevated temperature elasticity as well as washability and dryability. The inventive elastic article comprises a substantially cured, irradiated, cross-linked (or curable, irradiated or cross-linkable) homogeneously branched ethylene interpolymer characterized as having a density less than 0.90 g/cm3 and containing at least one nitrogen-containing stabilizer. The improved elastic article of the present invention is particularly suitable for use in applications where good elasticity must be maintained at elevated temperatures and after laundering such as, for example, elastic waist bands of undergarments and other clothing.</p> |
