A medical and dental curable composition containing a suspension polymerization method using a polymer surfactant synthesized by precision polymerization as a stabilizer and polymer fine particles synthesized thereby.

摘要

PROBLEM TO BE SOLVED: To easily obtain polymer beads having a desired particle size in suspension polymerization of an acrylic acid ester monomer, a methacrylic acid ester monomer and a styrene monomer without causing coalescence. Provide an activator. SOLUTION: A polymer surfactant represented by the following formula. In the formula, A has a chemical structure showing hydrophilicity, and B in the formula has a chemical structure showing hydrophobicity. Further, Z indicates a structure derived from the polymerization initiator. In the formula, a and b indicate the number of repetitions, and both are in the range of 10 to 1000.
