Abstract

A compound is of formula (I):in which A1 and A1′ are independently from each other a linear or branched alkylene radical including from 1 to 20 carbon atom(s); A2 is in particular a linear or branched alkylene radical including from 1 to 200 carbon atom(s); A3 is H or a linear or branched alkyl radical including from 1 to 15 carbon atom(s) and R1 and R1′ 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.
