And, as mentioned above, with the monomeric mixture of two or more free redical polymerizations during as monomer component (A), the absorption of water of this mixture itself can be calculated by arithmetical mean by the monomeric absorption of water of each free redical polymerization, and it is just passable therefore according to their ratio of mixture of target adjusting the absorption of water of monomer component (A) to be adjusted in the aforementioned range.For example, the monomeric mixture that uses the monomer of strong-hydrophobicity free redical polymerization and strongly hydrophilic free redical polymerization for absorption of water is adjusted in the aforementioned range, can use the monomer of strong-hydrophobicity free redical polymerization during as monomer component (A) in a large number.
And, in the present invention, as long as (promptly with the absorption of water of monomer component (A), the absorption of water of the monomer integral body of used free redical polymerization) is adjusted in the aforementioned range, can with the monomer of various free redical polymerizations separately or two or more mix and use, particularly, by a large amount of use two senses or the monomer more than the trifunctional, can make mechanical properties such as the intensity of cured article of final gained and weather resistance all good.
In addition, in solidification compound of the present invention, except aforementioned (methyl) acrylic acid or the like polymerisable monomer, for easily polymerization, regulate viscosity or regulate other rerum natura, also can mix the monomer that uses other free redical polymerization except that above-mentioned (methyl) acrylic acid or the like polymerisable monomer.In either case, the absorption of water of the monomer component of free redical polymerization is necessary for 20wt% or lower.The monomeric example of these other free redical polymerization can have been enumerated vinylbenzene or alpha-methyl styrene derivatives such as fumaric acid esters, vinylbenzene, Vinylstyrene, alpha-methyl styrene such as monomethyl fumarate, DEF, fumaric acid diphenyl ester; Allylic cpds such as diallyl p phthalate, Phthalic acid, diallyl ester, diallyl diglycol carbonates etc.The monomer of these other free redical polymerizations can use separately, and perhaps two or more are also used.
＜water (composition B) 〉
In solidification compound of the present invention, comprise in the matrix of aforementioned monomer composition (A) and be dispersed with water, under the state that is dispersed with water thus, be cured by radical polymerization, form cured article.Promptly, because water is carrying out radical polymerization under tensio-active agent dispersive state described later, therefore carrying out the polymeric suitable water layer (containing tensio-active agent) of formation on the cured article surface of formation simultaneously, this water layer suppresses oxygen invades in cured article, and the result can suppress to form on the cured article surface not polymkeric substance.
The aforementioned monomer composition (A) of relative 100 mass parts, the combined amount of this water are in 0.5～10 mass parts, and preferred 0.5～5 mass parts is most preferably in the scope of 1～3 mass parts.That is, the combined amount of water is many more, can reduce the not formation of polymkeric substance more, but the mechanical properties of cured articles such as opposite intensity and hardness has also reduced.And, when mixing water not and when in water, carrying out polymerizing curable, no problem from the angle that reduces the not formation of polymkeric substance, but the mechanical characteristics of cured article significantly reduces, or solidify not enough, solidification compound must be impregnated in the water, so the purposes of solidification compound obviously is restricted, for example can not be applicable to for example purposes such as dental repair materials.And, the present invention can aforesaid amount with water-dispersion in solidification compound.
＜tensio-active agent (composition C) 〉
In solidification compound of the present invention, tensio-active agent and water are mixed together.That is, by using tensio-active agent, carry out polymeric simultaneously can be on the surface of the cured article that forms the branch water distribution layer, thereby can reduce the not formation of polymkeric substance on the cured article surface effectively.
The aforementioned monomer composition (A) of relative 100 mass parts, this tensio-active agent uses with the amount of 0.1～20 mass parts.That is, same with water, the combined amount of tensio-active agent is many more, can reduce the not formation of polymkeric substance on the surface more, but the mechanical characteristics of cured article has reduced but.Therefore, the combined amount of tensio-active agent is in above-mentioned scope.
And, as tensio-active agent, can use in anionic property, cationic, amphoteric plasma type tensio-active agent and the nonionic surfactant any one.The specific examples of such tensio-active agent has no particular limits, and can be following material:
