SHEET-LIKE MOLDING MATERIAL AND LAMINATE FOR MOLDING CONTAINING THE MATERIAL AS ONE LAYER. |
摘要 |
<p>This new sheet-like moulding material comprises a propylene polymer (A), at least partially crosslinked, and filler. When (A) is extracted after boiling in xylene for three hrs., the amt. insol. in xylene is specified to be 5 wt.% or more (pref. 10-60 wt.%). The sheet-like material is produced by mixing a filler (10-50 wt.%), a radical generator (0.01-0.5 wt.%) and a cross-linking agent (0.05-5 wt.%) with the molten propylene polymer (100 wt.%), kneading them, and then making into a sheet. The crosslinking agent is specified to be a polymerisable monomer having at least one ethylene type unsatd. bond. The laminate comprises a core layer and surface layers. The core layer is at least partially made of the sheet-like moulding material. The surface layers are made of thermoplastic elastomer, fabric, polyvinylchloride, unwoven cloth or synthetic leather. A cushion layer made of the thermoplastic foams is formed between the core layer and the surface layers.</p> |
