PURPOSE:To strengthen the chemical bond propety with antigens or antibodies by a method whereine stylen or stylene and another monomer polymerizable therewith are polymerized in water with peroxosulfate as initiator without the presence of emulsifier and a compound containing amine reacts chemically upon a polymer particles in the suspension to have an amino group existing therein. CONSTITUTION:When a polymer particle is produced by polymerizing stylene with peroxosulfate as initiator, -SO3<-> on the surface of the polymer particle is changed to -OH group by hydrolysis. But when in the hydrolysis, the particle is subjected to a long-time heating in the coexistence of oxygen, it is oxidized to the extent of turning -OH group to -COOH group. Even in this case, with the polymer particle contacting alkylene imine such as ethyleneimine and propyleneimine, -COOH group on the surface of the particle is changed by chemical reaction with alkyleneimine to form a primary amine. Thus, amino group exists in the particle. In addition, when the stylene and another polymer polymerizable therewith are polymerized, -SO3<-> can be changed to -COOH group by hydrolysis thereof on the surface of the polymer particle through heating of the suspension. |
