FIVE-MEMBERED CYCLIC BISCARBONATES BEARING AMIDE LINKAGES, THEIR PREPARATION AND THEIR USES FOR THE PREPARATION OF POLYMERS

摘要

The invention relates to a compound of formula (I):
wherein A 1 and A 1 ' are independently from each other a linear or branched alkylene radical comprising from 1 to 20 carbon atom(s); A 2 is in particular a linear or branched alkylene radical comprising from 1 to 200 carbon atom(s); A 3 is H or a linear or branched alkyl radical comprising from 1 to 15 carbon atom(s) and R 1 and R 1 ' are independently from each other H or a linear or branched alkyl radical comprising from 1 to 20 carbon atom(s). The present invention concerns the compounds of formula (I), their preparation and their uses, in particular for the preparation of poly(hydroxyurethane)s.
