PROPYLENIC POLYMER COMPOSITION FOR ADHESIVES AND LAMINATES MADE BY USING THE SAME

摘要

A propylenic polymer composition for adhesives, capable of giving laminated structures which are free from lowering in bond strength by molding or heat treatment and from whitening on bending; and laminated structures made by using the composition. Specifically, a propylenic polymer composition (D) for adhesives which comprises (i) 40 to 92 wt% of a graft-modified polypropylene (A), (ii) 5 to 30 wt% of an ethylene/a-olefin copolymer (B) which exhibits a melt flow rate (MFR) of 0.01 to 10g/10 min at 230°C under a load of 2.16kg and a density of 0.940g/cm³ or below, and (iii) 3 to 30 wt% of a block copolymer (C) consisting of a crystalline olefin segment and an ethylene/a-olefin segment (with the proviso that the total sum of the components (A), (B) and (C) is 100wt%); and laminates comprising at least one layer containing the composition.
