It was the optimized synthesis condition of the hydrosilation reaction that the ratio of PHDS and APE was 1∶8, the reaction time was 4 h, the reaction temperature was 90～120. The softness of the paper using amino modified polyether-siloxane increased, but its tensile strength decreased.
Amino modified anionic emulsion copolymerization of cyclosiloxanes was favourably carried with Octamethylcyclotetrasiloxane (D\-4) as monomer, 3-Aminopropyltriethoxysilane (KH550) as amino modified monomer, dodecylbenzenesulfonate (DBSA) as catalyst and emulsifier. The structure of polymer synthesized were examined with infrared spectroscopy (IR).
Methods The amino modified wild-type and mutant probes of 16 loci (1888, 3200, 3206, 3243, 3290, 3316, 3394, 3593, 3426, 12026, 12258, 14577, 14693, 14709, 16189, 16223) in mitochondrial genome were immobilized onto the activated slides with aldehyde surface using Biochip Arrayer, then they were incubated overnight in a humid chamber at room temperature.
The amino modified polystyrene(NDA-900)had high sorption capacity and good kinetic property for sulfosalicylic acid. The adsorption kinetic data fitted to the Lagergren pseudo-second order rate equation. Intrapartical diffusion was the rate controlling step and could be described by HSDM model.
ostitutes of soft-agents of amino-modified silicone exported from RHONE-POULENC were separated and analyzed by CC、IR and TLC. In according to the result of the analysis, we choose a sort of surfactants, which were produced in our country and prepare emulsions of amino-modified silicone. Through the emulsified and appreciated we find that the emulsion and soft nearly has the same effect as exported BC-610 soft-agents surfactant.
