Title
(EN) COMPOSITIONS COMPRISING PROPYLENE-BASED ELASTOMERS AND POLYALPHAOLEFINS
(FR) COMPOSITIONS COMPRENANT DES ÉLASTOMÈRES À BASE DE PROPYLÈNE ET DES POLYALPHAOLÉFINES
Abstract
(EN)
Provided are compositions comprising a propylene-based elastomer and a polyalphaolefin. The compositions may be particularly useful in elastic film compositions, and especially useful as elastic film layers in nonwoven laminates.
(FR)
La présente invention concerne des compositions comprenant un élastomère à base de propylène et une polyalphaoléfine. Ces compositions peuvent être particulièrement utiles dans des compositions pour film élastique, et particulièrement comme couches de film élastique dans des stratifiés non tissés.
