| titleOfInvention | Method for producing by continuous bulk polymerization of amphoteric electrolyte resin and apparatus therefor |
| abstract | The present invention provides a process for producing an amphoteric electrolyte resin at low cost by continuous bulk polymerization. The invention also provides an apparatus for carrying out the method. The process comprises the following steps: 0.01 to 10% by weight of at least one radically polymerizable basic monomer containing a nitrogen atom, 0.01 to 35% by weight of at least one radically polymerizable acidic monomer having a carboxyl group, and these Mixtures comprising 45 to 99.98% by weight of monomers copolymerizable with monomers or mixtures of said mixtures with organic solvents having a boiling point of at least 80 ° C in an amount of up to 10% by weight relative to the total weight of the polymerization initiator and / or said monomers Feeding from the mixture feed side to a reaction zone comprising four polymerization zones each independently providing a mixture temperature of T 1 , T 2 , T 3 and T 4 ; Subsequently, while stirring the mixture, continuously passing the reaction zones so that the residence time in each polymerization zone is 5 to 20 minutes, provided that T 1 , T 2 , T 3 and T 4 satisfy the following requirements: T 1 = 50 to 160 ° C, T 2 = 70 to 190 ° C, T 3 = 70 to 250 ° C, T 4 = 70 to 270 ° C, and T 1 <T 2 , T 2 ≤ T 3 and T 3 ≤ T 4 ; And one pass of the reaction zone can produce a copolymer having a reaction rate of at least 85%. By using the above method, a positive electrolyte resin having a number average molecular weight of 700 to 6,000 and an Mw / Mn ratio of 1.5 to 10 can be produced by continuous bulk polymerization. |
