AI Technical Summary

Technical Problem

Conventional polymerizable compositions face issues where imparting antibacterial or antiviral properties leads to deterioration in the appearance of the cured product.

Method used

A method involving dispersing a solution of a second polymerizable monomer in a first polymerizable monomer using a solvent, with the addition of a surfactant, to uniformly localize the second monomer, thereby imparting antibacterial or antiviral properties without affecting the appearance or strength of the cured product.

Benefits of technology

The method ensures that antibacterial or antiviral properties are effectively imparted to the cured product while maintaining its appearance and mechanical strength.

Abstract

To provide a method of manufacturing a polymerizable composition by which it is possible to impart antibacterial properties and the like to a cured product of the polymerizable composition without causing a deterioration in the appearance of it.SOLUTION: The present invention discloses a method of manufacturing a polymerizable composition having a solution dispersed in a first polymerizable monomer, the solution including a second polymerizable monomer dissolved in a first solvent. The method of manufacturing the polymerizable composition includes the step of mixing the first polymerizable monomer, the second polymerizable monomer, and the first solvent. The first polymerizable monomer is a liquid, and the second polymerizable monomer is a solid.SELECTED DRAWING: None
