The interaction parameters of MB and BSA and simulated albumin such as partition coefficientκ、 normal binding free energyΔ G、 average binding number n are calculated. The results show that most of MB is in the form of monomer in SDS micelle systems； the main interaction of MB and BSA is of static electric and H-bind force,and that of MB and simulated albumin is only of static electric force.展开更多
The aluminosiloxane sol was prepared by the reaction of mixture of 2-methylacrylic acid with soldium silicate and aluminium nitrate. A soap-free emulsion polymerization of the methyl methacrylate-K2SO2-H2O system was ...The aluminosiloxane sol was prepared by the reaction of mixture of 2-methylacrylic acid with soldium silicate and aluminium nitrate. A soap-free emulsion polymerization of the methyl methacrylate-K2SO2-H2O system was carried out using aluminoxane sol to prepare aluminosilox-ane-PMMA. The products were characterized by IR, TGA, DSC, DTA and SEM. The resultis revealed that the surface of aluminosiloxane was chemically bound to the polymer.展开更多
