4 Claims

1. A method of producing a polymerizable composition, the method comprising:

dissolving (i) a portion of a first polymerizable monomer and (ii) a second polymerizable monomer in a solvent to obtain a first solution;

heating the first solution to copolymerize the portion of the first polymerizable monomer and the second polymerizable monomer to obtain a second solution;

mixing the second solution with at least a portion of a remainder of the first polymerizable monomer to obtain a third solution;

evaporating the solvent from the third solution to obtain a dispersion liquid in which the copolymer of the second polymerizable monomer is dispersed in the first polymerizable monomer; and

after the evaporating step, mixing and kneading the dispersion liquid and a filler,

wherein the first polymerizable monomer is a liquid at room temperature and atmospheric pressure, and

wherein the second polymerizable monomer is a solid at room temperature and atmospheric pressure.
