Abstract
Provided is a carbodiimide-modified, high-density polyolefin-based adhesive with minimal lowering of adhesion power even in a high temperature environment, and a laminate having excellent interlayer adhesion power at high temperatures prepared by using the adhesive. Provided is an adhesive obtained by reaction of a polyolefin (A) having a group reactive with a carbodiimide group and a compound (B) containing a carbodiimide group in the presence of an unmodified polyolefin (C), having a ratio of a peak intensity at 2130 to 2140 cm−1 to a peak intensity at 1470 cm−1 of 50% or less (but not including 0%).
Claims5
An adhesive for extrusion molding obtained by reacting a polyolefin (A) having a group reactive with a carbodiimide group and a compound (B) containing a carbodiimide group in the presence of an unmodified polyolefin (C),
- wherein said adhesive has a ratio of a peak intensity at 2130 to 2140 cm−1 to a peak intensity at 1470 cm−1 of 50% or less and not including 0%, and
- a polyolefin having a density of 0.925 to 0.980 g/cm3 is used as a raw material of a polyolefin (A) having a group reactive with a carbodiimide group.
An adhesive obtained for extrusion molding by reacting a polyolefin (A) having a group reactive with a carbodiimide group and a compound (B) containing a carbodiimide group in the presence of an unmodified polyolefin (C) at 250 to 270° C.,
- wherein said adhesive has a ratio of a peak intensity at 2130 to 2140 cm−1 to a peak intensity at 1470 cm−1 of 50% or less and not including 0%, and
- a polyolefin having a density of 0.925 to 0.980 g/cm3 is used as a raw material of a polyolefin (A) having a group reactive with a carbodiimide group.
