  申请人：Upshaw Thomas A.

  公开号：US20090264669A1

  公开（公告）日：2009-10-22

  The application discloses thiol ester molecules and α-hydroxy thiol ester molecules having a thiol group located on one of the final two carbon atoms in a carbon chain or a terminal or α-hydroxyl groups, respectively. The disclosed thiol ester molecules and or α-hydroxyl thiol ester molecules es may be made from unsaturated ester molecules having one or more terminal alkene groups. The disclosed techniques also provide methods for making unsaturated ester molecules having one or more terminal alkene groups by the metathesis of unsaturated esters having one or more internal carbon-carbon double bonds (e.g. natural source oils). The thiol ester molecules or α-hydroxy thiol ester molecule may be used in reactions with isocyanate monomers, epoxide monomer, or material having multiple alkene groups to make sealants, coatings, adhesives, and other products.
