Abstract
This invention provides a novel polyolefin modified with a nitrogen-containing heterocyclic compound containing no harmful halogen atoms such as chlorine, and an adhesive composition between a polyolefin substrate and an inorganic substrate such as a glass substrate. A polyolefin modified with a nitrogen-containing heterocyclic compound (C) having a nitrogen-containing heterocyclic compound (B) at the side chain of an acid-modified polyolefin (A).
Claims14
A polyolefin modified with a nitrogen-containing heterocyclic compound (C) having a nitrogen-containing heterocyclic compound (B) at a side chain of an acid-modified polyolefin (A),
- wherein the amount of the nitrogen-containing heterocyclic compound (B) is 3.9 to 7 mass %.
A composition of a polyolefin modified with a nitrogen-containing heterocyclic compound containing:
- a polyolefin modified with a nitrogen-containing heterocyclic compound (C) having a nitrogen-containing heterocyclic compound (B) at a side chain of an acid-modified polyolefin (A),
- wherein the amount of nitrogen-containing heterocyclic compound (B) is 3.9 to 7 mass %;
- and
- an organic solvent (D), wherein
- the organic solvent (D) is a mixture of a solvent (D1) and a solvent (D2),
- the solvent (D1) is at least one solvent selected from the group consisting of aromatic hydrocarbons, aliphatic hydrocarbons, alicyclic hydrocarbons, and halogenated hydrocarbons,
- the solvent (D2) is at least one solvent selected from the group consisting of alcohol-based solvents, ketone-based solvents, and ester-based solvents, and
- the ratio of the solvent (D1)/solvent (D2) is 60 to 98/40 to 2 (mass ratio).
