Abstract: A process for the manufacturing of a polymer with urethane groups can be performed. In a first alternative a five-membered cyclic monothiocarbonate, a compound with at least two amino groups selected from primary or secondary amino groups, and a compound with at least two function groups that react with a —SH group are reacted. In a second alternative a five-membered cyclic monothiocarbonate and a compound with at least one primary or secondary amino group, and at least one function group that reacts with an —SH group are reacted.
