Enzyme-medicated cross-linking of silicone polymers 

Zelisko, Arnelien and  Frampton of Canada, cross-linked silicone polymers by contacting a silicone polymer and a cross-linking agent with a hydrolytic enzyme under conditions for the cross-linking of the silicone polymer, wherein the silicone polymer has been modified to comprise functional groups that react with the hydrolytic enzyme.  Trypsin and pepsin effectively catalyzed the cross-linking of .alpha.,.omega.-(triethoxysilyl)ethyl-polydimethylsiloxane (TES-PDMS), similar to dibutyltin dilaurate.  Studies showed little difference between the products of the dibutyltin dilaurate- and trypsin-catalyzed systems.  (RDC 3/6/2013)
