- Example 11 PEB / SEBS / tBCHA / 4HBA: 35/35/30/10 ⁇ ⁇ 100 100 1.32 0.91 100
- ⁇ Methyl methallylate
- tBCHA Acrinoleic acid 4-t-hexyl hexole
- tBCHMA Metharylic acid 4-t-butylhexyl hexyl MM: Ataryl acid
- CHA Atalinoleic acid mouth hex / res tBMA: t-butyl methacrylate
- IBXMA Isobornyl methacrylate
- the polyolefin resin (A) is prepared by adding an atalyloyloxy group or a methacryloyloxy group to a secondary or tertiary carbon atom (meth). Since it contains a modified polyolefin resin graft-modified with a butyl monomer (B) containing an acrylate monomer (b), it has solubility in solvents and poor adhesion to polyolefin resins. Good adhesion to the material.
- the modified polyolefin resin composition of the present invention is excellent in adhesion to not only a non-polar base material made of a polyolefin resin but also a top coating material (clear paint), so that it is suitable for use as a paint primer.
- the modified polyolefin resin composition of the present invention has an adhesive property not only to a non-polar base material made of a polyolefin resin but also to a polar resin such as polyester, polyurethane, or polyamide, so that it is used for an adhesive or a printing ink. Suitable for.
