Grafting Onto

Poly(methyl methacrylate)/SiO2(PMMA/SiO2) hybrid composites were prepared via “grafting onto” strategy based on UV irradiation in the presence of iron aqueous solution. Two steps were used to graft polymethyl methacrylate (PMMA) onto the surface of nanosilica, anchoring 3-(methacryloxy) propyl trimethoxysilane (MPTS) onto the surface of nanosilica to modify it with double bonds, and then grafting PMMA onto the surface of nanosilica with FeCl3as photoinitiator. The products were characterized by FT-IR, TGA, TEM, DLS, and XPS. The results showed that it is easy to graft PMMA onto the surface of nanosilica under UV irradiation, and the hybrid particles are monodisperse and have core-shell structure with nanosilica as the core and PMMA layers as the shell. Furthermore, the products initiated by FeCl3have higher monomer conversion, percent grafting, and better monodispersion compared with the products initiated by traditional photoinitiator such as 2-hydroxy-4-(2-hydroxyethoxy)-2-methyl-propiophenone (Irgacure 2959).

The heparin-poly(methyl methacrylate) copolymer was prepared by polymerization of methyl methacrylate on an heparin radical. It was initiated by cerium IV ions and heparin in nitric aqueous solution.An heparin effect was present in the plasma in contact with the copolymer. It was not due to a release of heparin in the plasma, but to a contact effect. The anticoagulant effect was depending upon the concentration of the copolymer. The activity of clotting factors in plasma, after a contact with the copolymer was not decreased except for factor V. Antithrombin III was selectively adsorbed on the surface of the copolymer.The copolymer lost progressively its anticoagulant properties after each contact with the plasma. This might be due to the adsorption of fibrinogen on the copolymer. Labelled 125I albumin, transferrin, Ig G and fibrinogen were not similarly desorbed in the presence of serum and of plasma.This copolymer seems to offer interesting properties for blood devices.
