摘要：The present techniques relate to thiourethane compositions formed byreacting a reactive composition containing active molecules having an average of at leastone thiol group per active molecule and an average of at least one hydroxyl group peractive molecule with a monomer composition containing monomer molecules having anaverage of at least two isocyanate groups per monomer molecule. The reactions areperformed in the presence of an amine catalyst, which may preferentially react thiolgroups over hydroxyl groups, thus forming a thiourethane composition having, onaverage, more hydroxyl groups than thiol groups and more thiourethane groups thanurethane groups, on a normalized basis.
