Polythiols with carbamate groups

摘要

The present invention discloses polythiol compositions containing sulfur-containing compounds with carbamate groups, and to methods for producing such polythiol compositions. These polythiol compositions can be synthesized via the reaction of an isocyanate with an allyl ether alcohol, followed by thiolation with H2S, and these polythiol compositions are often used in formulations for adhesives, paints, and coatings.
