Surface photografting polymerization (SPGP) may be intiated by the photoredution reation of an aromatic ketone with a surface H-donors

the chain transfer of a free radical to the surface of organic materials

as well as the fragmentation of a special photo-sensitive group on the surface of materials.SPGP may be conducted by a vapor phase process

a liquid phase process or a bulk phase process.The previous applications of SPGP are surface modification of organic materials

especially polyolefins.The main properties modified by SPGP are adhesiveness

printability

paintability

dyeability

anti-fogging properties

gloss

anti-static properties

lubrication

anti-staining properties

bio-compatibility

heat sealability

and so on.In recent years

extensive researches have been reported for the functionalization of a polymer surface

e.g.

the preparation of separation membrane

polymer-supported catalysts

reagents

ligands for absorption of metal ions

as well as polymer forming method.
