New (meth)acrylic compounds, process for their preparation and their use in the synthesis of new polymers.

摘要

These compounds are represented by the following formula (I): <IMAGE> in which: - Z represents H, or a linear or branched alkyl radical; - X represents O or S; - A and B each independently represent an alkylene radical, it being possible for this radical to be substituted; - R represents H or an alkali metal, or else a linear or branched alkyl radical; - x has a value 0 or 1; and - y has the value 0, 1 or 2; the A radical not existing if x and y are both equal to 0, it not being possible for X to represent O when R = alkyl and when R = H with x = y = 0, and it not being possible for B to represent optionally substituted methylene when X = S, x = y = 0 and R = alkyl. According to the invention, various simple and efficient processes for preparing these new compounds, applicable to the preparation of new polymers and copolymers, are proposed.
