Document Type and Number:

WIPO Patent Application WO/2007/086434

Kind Code:

A1

Abstract:

A laminate produced by coextrusion molding and including a fluorocopolymer having excellent interlaminar adhesion strength. The laminate can be made satisfactorily usable even at high temperatures or in applications where it comes into contact with an oil, gasoline, or the like, by regulating properties of the adhesive layer. The laminate is composed of at least two layers comprising a structure obtained by bonding and superposing an adhesive (A) defined by the following (i) to (iii) and a fluorocopolymer (B). The adhesive (A) is (i) an adhesive obtained by reacting a polyolefin (a) having a group reacting with a carbodiimide group with a compound (b) having a carbodiimide group, and (ii) in analysis by infrared absorptiometry, the ratio of the peak strength at 2,130-2,140 cm-1 to the peak strength at 1,470 cm-1 is 60% or lower and (iii) the adhesive has a density of 0.870-0.940 g/cm3.
