- the subject of the present invention is polymers comprising at each of their ends a 1,3-dioxolan-2-one (or cyclocarbonate) end group linked to a polymeric chain by an alpha (a) substituted methylether (CH 2 -O) function.
- These polyurethanes once formulated, are intended for use in coatings, mastics or adhesives, as additives and / or as resins.
- diisocyanates are toxic compounds as such, and are generally obtained from phosgene, itself very toxic by inhalation or contact.
