These resins are usually used with organic flooding agents as a medium, but
From social viewpoints such as environmental conservation and resource conservation, there is an urgent need to convert these to water dispersions. For this reason, development of techniques for making these resins into a water bath or dispersing them in water is being carried out in various fields.

There are drawbacks such as f and c that the surfactant is eluted from the film. On the other hand, the hydrophilic group grafting method (4) is superior in that it imparts self-emulsifying ability to water, but requires a large amount of organic solvent to be used in eight volumes because the reaction is carried out in an organic solvent, and the reaction operation is complicated. Due to certain reasons, there are relatively few concrete implementation methods. A relatively recent proposal has been made, for example, in JP-A-53-1228, in which an epoxy resin is processed into a water-bathable vinyl compound (
There is a method of graphing α, β-unsaturated carboxylic acid) and dispersing it in water. However, with this method, (a) it is difficult to remove a large amount of organic bath agent and residual monomer;
Not only is the grafting efficiency low and stability is poor, but the grafted product and non-grafted product are likely to undergo phase separation.

For this reason, there are drawbacks such as deterioration of film properties. As a method to solve these drawbacks, a method of grafting a mixture of an epoxy resin and a polymerizable monomer group including an unsaturated monomer having a carboxyl group by electron beam irradiation to form an aqueous dispersion (especially 1973-32551) was recently proposed. However, the epoxy resin latex obtained by this method has a large particle size and its distribution, lacks storage stability, and has uneven curing reaction within the same day, and is inferior in water resistance, solvent resistance, and physical properties. 7hi has this drawback.

As a result of intensive research to obtain a chemically stable water dispersion resin with excellent water resistance, solvent resistance, physical properties, etc., we found that in order to obtain a water dispersion, we carried out graft polymerization. The resin is first dissolved or swollen in a small amount of solvent, and then alkaline or acidic water is added to make it water-dispersible, but the particle size of the dispersion is already determined at the stage of dissolving or swelling in a small amount of solvent. It has been found that the key to obtaining an aqueous dispersion with a small particle size and particle size distribution is to graft-polymerize a hydrophilic monomer with low compatibility with the resin.

Did you limit the irradiation temperature to 150t? This is because cooling to a temperature lower than that is not only disadvantageous in terms of cooling cost but also leads to a decrease in the reaction rate, and irradiation at 50C or higher may cause a crosslinking reaction. i! The quantity ratio is limited not only by the performance of practical equipment but also by the reaction aspect. That is, if the dose rate is too low, the molecular weight will increase significantly or a crosslinking reaction will occur, resulting in gelation, making water dispersion impossible. In addition, at the muscle dose rate, the heat generation associated with irradiation is extremely large. f? ) or because the radical concentration increases, recombination reactions increase, making it difficult to control the reaction or causing gelation. The amount of wood is limited by the performance of practical equipment, but with regard to the irradiation dose, a dose of 5 Mrad or less will result in a large amount of residual monomer, and on the other hand, a thick dose of 50 Mrad or more is not necessary and is rather a waste of time. This will lead to other harmful effects. The solidified product obtained by irradiation is pulverized by an appropriate method to an average particle size of about 1 M or less, dissolved or swollen in an organic solvent, and mixed with water and stirred to obtain an aqueous dispersion.
