Applications promote new characterization of graft chains

Processes of graft polymerization of vinyl monomers onto preirradiated films and nonwoven fabrics have been continuously operated on a commercial scale [1]. Radiation-induced grafting is still promising for the following reasons. 

U) Various shapes of trunk polymers can be supplied in response to the demanded functionality adsorbents based on porous hollow-fiber membranes and nonwoven fabrics enaWe high-speed recovery of target molecules and ions by utilizing convective flows through the pores of the membranes and among the fibers, respectively. 

New applications have been suggested to highlight the features of the grafted polymer branches. 

Insuffident characterization of the graft chains does not mean unsatisfactory materials with resped to spedfic fundionality. The high performance of fundional polymeric materials prepared by radiation-induced graft polymerization and subsequent chemical modifications has been verified experimentally. Moreover, phenomena such as multilayer binding of proteins to the graft chains [7-11,16-18] and
