Improvement in Dyeing and Water Absorption Properties of Polypropylene and Polyethylene

Abstract

The surface properties of polyolefin materials such as polypropylene (PP) and polyethylene (PE) were improved using a combination of activation treatment and polymer or monomer grafting. These materials obtained have a high water absorption property, and improved dyeing and painting properties, bonding with usual adhesives, etc. and are expected to be used widely in many fields. The technique is useful for the improvement of other polymeric materials.
