Title:
POLYMER COMPOSITION FOR LAMINATION AND LAMINATE USING THE SAME
Document Type and Number:
Japanese Patent JP2021001329
Kind Code:
A
Abstract:
To provide a polymer resin composition for lamination using an ionomer which is excellent in workability and hot tack strength, and a laminate.SOLUTION: A composition contains (X1) 100-60 wt.% of an ionomer in which at least a part of a carboxyl group and/or a dicarboxylic acid anhydride group in a copolymer (P) containing a structural unit (A) derived from ethylene and/or α-olefin having 3-20 carbon atoms and a structural unit (B) derived from a monomer having a carboxyl group and/or a dicarboxylic acid anhydride group as essential structural units is converted into a metal-containing carboxylate containing at least one metal ion selected from Group I, II or XII in the periodic table, and a phase angle δ at an absolute value G*=0.1 MPa of complex modulus of elasticity measured by a rotary type rheometer is 50-75 degrees; and (X2) 40-0 wt.% of an ethylenic copolymer containing ethylene by high pressure radial polymerization as an essential monomer.SELECTED DRAWING: None
