The conclusion that carboxonium ions are the reactive centres for polymerization of cyclic acetals hasbeen reached on the basis of our own and literature data. A modified mechanism of the chain propagation reaction, S N1 is suggested and is based on a synchronous carboxonium ion formation as ...
Influence of Water Activity and Maillard Reaction on the Polymerization of Myosin Heavy Chain in Freeze-dried Squid Meat Brown discoloration of freeze-dried short-finned squid meat imparted by the Maillard reaction during storage at 25掳C was examined as a function of water a... M Tanaka,N Ch...
Synthesis of copolymer MA and CVE were copolymerized by free-radical solution polymerization. Typically, specific amounts of MA, CVE, 2,2¢-azobisisobutyronitrile and solvent were added to a 50 ml three-neck flask equipped with a condenser and a nitrogen gas inlet. The reaction solution was ...
The reaction combines oxidative polymerization and in situ reductive n-doping, greatly increasing the doping efficiency, and a doping level of almost 0.9 charges per repeating unit can be achieved. The resultant polymer exhibits a breakthrough conductivity of more than 2,000 S cm−1 with ...
The invention provides a method of making an amide-type polymer/silicone polymer blend comprising the steps of preparing a silicone polymer emulsion comprising a silicone polymer dispersed in a liquid continuous phase; introducing the silicone polymer emulsion into an amide-type polymerization reaction me...
In this work, the yield of reaction was measured using a gravimetric method. The yield of reaction and number-and weight-average degree of polymerization of polymer particles were found to be dependent on the non-solvent type and purification process. When the solubility parameter differences of ...

The final equations of the first set describe the formation of products C and D as sequential, and the second set descibes it as parallel. However, if a steady-state or quasi-steady-state reaction is under examination both descriptions are equivalent. If the rates r(1) and r(2) along ...
However, aldol-GTP of Z- BdTMS also reacted with benzaldehyde may BdTMS gave neither a polymer nor 1 : 1 aldol be caused by the different reaction conditions adduct of BdTMS and AAld (run 6). from those of polymerization. Aldol-GTP of E- and Z-BdTMS mixture gave Figure 2 shows ...
