Chemcontrol Urethanes

Polyurethane (PUR)

This important class of polymers is formed by the addition polymerization of an diisocyanate (whose molecules contain two –NCO groups) and a dialcohol (two –OH groups). The polymer chain is linked by urethane groups (–O–CO–NH–). The –NH– portion of the urethane group can react similarly to an –OH group, producing cross-linking between polymer chains.
