Grafting to technique for synthesis of polymer films

The density of the brush obtained by the grafting to method can be increased if the macromolecule attachment is conducted from a solution at 0 conditions or from melt. Grafting from melt in particular offers 

An additional increase in grafting density for the attachment from the melt can be achieved when the PGMA anchoring layer is used for the introduction of reactive group on a substrate surface. Attachment 

4 Surface coverage, r(mg/m ) versus degree of polymerization (A/) of grafted PS chains.
