| titleOfInvention | Producing method of anion polymer using reaction short stop agent anti-discoloration |
| abstract | The present invention is a method of producing a rubber with a discoloration resistant and pure color in the production of anionic polymers, especially 1,3-butadiene rubber, the polymerization of n-butyllithium as an initiator after the polymerization of MADPS added as a dispersant in the flocculation step The sodium salt is partially acidified (the degree of acidification is 1 to 100%, and the degree of acidification is the ratio of the absolute amount of sodium and hydrogen in the carboxyl group).n n n MADPS removes lithium salt by adding 0.010 phr to 1.000 phr based on the amount of 1,3-butadiene monomer and Irganox 1076 / 1520L type is used as antioxidant. It is not necessary to add a dispersant in the process of recovering rubber.If only calcium chloride is added as a coagulant, sodium salt is substituted with calcium salt in MADPS used as a reaction terminator, and it becomes hardly soluble salt. It can be prepared, the rubber does not cause a problem in waste water pollution and increases the resistance to temperature can be produced a rubber that is hardly discolored. |
