Title: Preparation of gel hydrate
Inventor: TANIGUCHI YASUO
IPC: C08J5/00
Filed: 1980-05-07
Abstract: PURPOSE: To obtain a gel hydrate in a short time, by heating an aqueous solution of a saponified product of a vinyl acetate copolymer copolymerized with an ethylenically unsaturated fatty acid in the presence of a persulfuric salt.  
     CONSTITUTION: An aqueous solution of a saponified product of a vinyl acetate copolymer copolymerized with an ethylenically unsaturated fatty acid is heated in the presence of a persulfate. It is preferable that the content of an ethylenically unsaturated fatty acid to be copolymerized with vinyl acetate in the copolymer is about 1.8mol% or more. Even with the content of the fatty acid less than about 1.8mol%, an aqueous solution of the saponified product of the copolymer shows a tendency of gelling and increasing its viscosity in the presence of a persulfate, but this solution has a flowability and cannot be considered to be a gel. It is preferable that the polymerization degree of the saponified product of a copolymer of an ethylenically unsaturated fatty acid and vinyl acetate is about 1,000 or more, because the saponified product having a high polymerization degree can easily produce a gel hydrate even when the concentration of its aqueous solution is low so that such a saponified product is preferable.

IPC: B60R25/24
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To allow a receiver receiving a prescribed radio wave sent intermittently from plural transmitters to register efficiently an identification number(ID) of each transmitter. SOLUTION: The receiver is set to the ID registration mode (S1), and an ID of a transmitter 1 is registered to an ID registration memory 1 (hereinafter called ID memory 1) by sending a radio wave from the transmitter 1 (S21). In this case, the transmitter 1 sends a radio intermittently and the receiver excludes the ID registered in the ID memory 1 within a prescribed time from the registration condition of the ID memory 2 (S4-S8) to prevent that the ID of the transmitter 1 successively registered in the ID memory 2. Similarly the ID of the transmitters is registered in ID memories 2, 3.
