    Abstract: These compounds are denoted by the following formula (I): ##STR1## in which: Z denotes H or a linear or branched alkyl radical,X denotes O or S,each of A and B independently denotes an alkylene radical, it being possible for this radical to be substituted,R denotes H or an alkali metal, or else a linear or branched alkyl radical,x has the value of 0 or 1, andy has the value of 0, 1 or 2,the radical A not existing if x and y are both equal to 0, X being incapable of denoting O when R=alkyl and when R=H with x=y=0, and B being incapable of denoting optionally substituted methylene when X=S, x=y=0 and R=alkyl.According to the invention, different simple and efficient processes are proposed for preparing these new compounds, which can be applied to the preparation of new polymers and copolymers.

    Abstract: Superior artificial teeth, dentures, other dental replacement parts and dental prosthetic articles and devices, which exhibit high abrasion resistance, stability to moisture and which do not undergo volume changes, are obtained by polymerization of a compound of the formula ##STR1## in which R is H or -CH.sub.3, X is an alkylidene or the -SO.sub.2 -group, Y is an oxyalkylene group having between 2 and 5 carbon atoms, or an alkylidene group having between 1 and 5 carbon atoms. In some instances, the polymerization is carried out in the presence of a filler.
