Title:
BLOCK POLYMER AND ADHESIVE CONTAINING BLOCK POLYMER, WATER DISPERSION AND RESIN MODIFIER
Document Type and Number:
Japanese Patent JP2021183688
Kind Code:
A
Abstract:
To provide a block polymer to be an adhesive that gives adhesion to a polyolefin base material at high temperatures (80-100°C) and a modification effect with excellent thermal creep resistance.SOLUTION: A block polymer (Y) contains an acid-modified polyolefin (a) block and a polyamide (b) block. The acid-modified polyolefin (a) contains a polyolefin (A) having a carbon-carbon double bond and an unsaturated (poly)carboxylic acid (anhydride) (B) as constituent monomers. The acid-modified polyolefin (a) satisfies requirements (1)-(3). The polyolefin (A) contains ethylene and α-olefin (C3-8) as constituent monomers. The weight ratio between the ethylene and α-olefin (C3-8) [ethylene/α-olefin] as constituent monomers is 5/95-50/50.SELECTED DRAWING: None
