THERMOPLASTIC ELASTOMER COMPOSITION

Title:

THERMOPLASTIC ELASTOMER COMPOSITION

Document Type and Number:

WIPO Patent Application WO/1998/017722

Kind Code:

A1

Abstract:

A thermoplastic elastomer composition which can give, over a wide range of molding temperatures, a sheet excellent in uniform stretchability and emboss retention. The composition is obtained by dynamically heating in the presence of an organic peroxide a composition (I) comprising (A) 10 to 75 % by weight of a crystalline propylene polymer resin and (B) 90 to 25 % by weight of a propylene/olefin copolymer rubber to prepare a cross-linked polymer (II), and blending the polymer (II) with (C) 5 to 200 % by weight of at least one resin having a density of 0.94 g/cm?3� or lower and selected among ethylene copolymers and crystalline propylene polymers.
