AI Technical Summary

Technical Problem

Polyolefins have insufficient compatibility and adhesion with polar resins such as polyesters and polyphenylene sulfide, and existing grafting modification methods are unable to form sufficient adhesive strength in a short period of time.

Method used

Carbodiimide monomers with carbodiimide groups and polymerizable double bonds are used to graft-modify polyolefins to form graft-modified products, which improve the adhesion to polar group materials.

Benefits of technology

It forms a layer with high bonding strength in a short time, which significantly improves compatibility and adhesion with polar substrates such as polyester or polyphenylene sulfide.
