A compound is of formula (I): in which Aand A' are independently from each other a linear or branched alkylene radical including from 1 to 20 carbon atom(s); Ais in particular a linear or branched alkylene radical including from 1 to 200 carbon atom(s); Ais H or a linear or branched alkyl radical including from 1 to 15 carbon atom(s) and Rand R&#x2032; are independently from each other H or a linear or branched alkyl radical comprising from 1 to 20 carbon atom(s). The compounds of formula (I) can be used in particular for the preparation of poly(hydroxyurethane)s and epoxy resins.
