| Abstract Scope |
A composite material titanium (Ti)/ poly methyl methacrylate (PMMA)-co- n-butyl methacrylate (PBMA) (PMMA-co-PBMA) was developed with “grafting from” method to reduce stress shielding. A 3-step method was developed: (i) an alkali treatment of Ti surface, (ii) its functionalization with a phosphonic acid-containing polymerization initiator and (iii) controlled radical polymerization of MMA and BMA from this initiator.
This study deals with the characterization of the cut grafted copolymer without its degradation. For this, a new photocleavable initiator was designed. The grafting density, molecular weight and also melting point of PMMA-co-PBMApolymer brushes grafted on Ti were determined. |
