Embodiment 1
[0257]
[0258] 100 parts of styrene, 1.0 parts of sodium dodecylbenzenesulfonate, 100 parts of ion-exchanged water, and 0.5 parts of potassium persulfate were placed in a reactor equipped with a stirrer, and polymerized at 80° C. for 8 hours. Thus, an aqueous dispersion of seed polymer particles A having an average particle diameter of 60 nm was obtained.
[0259]
[0260] 2 parts of aqueous dispersion of the seed polymer particles A obtained in the step (1) (based on the solid content, that is, based on the weight of the seed polymer particles A), 12 parts in a reactor equipped with a stirrer 0.2 parts of sodium alkylbenzenesulfonates, 0.5 parts of potassium persulfate, and 100 parts of ion-exchanged water were mixed to obtain a mixture, and the temperature was raised to 80°C. On the other hand, in another container, 97 parts of styrene, 3 parts of methacrylic acid, 4 parts of t-dodecyl mercaptan, 0.5 parts of sodium dodecylbenzenesulfonate, and 100 parts of ion-exchange...
Embodiment 2
[0288] Instead of the non-conductive organic particles obtained in steps (1) to (3) of Example 1, the following non-conductive organic particles were used. Moreover, instead of the binder for porous membranes obtained in the process (4) of Example 1, the following binder for porous membranes was used. Using the non-conductive organic particles and the binder for the porous film to produce a porous film slurry, except that, the same operation as in Example 1 was carried out to obtain an organic separator with a porous film and a secondary battery, and carried out evaluate. The results are shown in Table 1.
[0289]
[0290] 10 parts of the aqueous dispersion of the seed polymer particles B obtained in step (2) (based on the solid content, that is, based on the weight of the seed polymer particles B), monomer Mixture (mixture of divinylbenzene and ethylvinylbenzene, monomer mixing ratio: divinylbenzene / ethylvinylbenzene=60 / 40, manufactured by Nippon Steel Chemical Co., produ...
Embodiment 3
[0300] Instead of the non-conductive organic particles obtained in steps (1) to (3) of Example 1, the following non-conductive organic particles were used. Moreover, instead of the binder for porous membranes obtained in the process (4) of Example 1, the following binder for porous membranes was used. Using the non-conductive organic particles and the binder for the porous film to produce a porous film slurry, except that, the same operation as in Example 1 was carried out to obtain an organic separator with a porous film and a secondary battery, and carried out evaluate. The results are shown in Table 1.
[0301]
[0302] 10 parts of the aqueous dispersion of the seed polymer particles B obtained in step (2) (based on the solid content, that is, based on the weight of the seed polymer particles B), monomer Mixture (mixture of divinylbenzene and ethylvinylbenzene, monomer mixing ratio: divinylbenzene / ethylvinylbenzene=60 / 40, manufactured by Nippon Steel Chemical Co., Ltd.,...
