Abstract
Abstract 3,4,5-TRITHIAPOLYCYCLO COMPOUNDS ARE PRODUCED BY REACTING A NORBORNENYL COMPOUND WITH SULFUR USING AMMONIA AS CATALYST. THE REACTION IS CARRIED OUT BY HEATING A CATALYZED MIXTURE OF THE NORBORNENYL COMPOUND AND SULFUR AT A TEMPERATURE ABOVE ABOUT 85*C. 3,4,5-TRITHIATRICYCLO (5.2.1.0**2,6)DECANE IS PRODUCED FROM BICYCLO(2.2.1)HEPT-2ENE AND SULFUR. THE TRITHIAPOLYCYCLO COMPOUNDS CAN BE POLYMERIZED TO SULFUR CONTAINING POLYMERS OR THEY CAN BE CONVERTED TO THEIR CORRESPONDING DITHIOLS; THEY ARE ALSO INHIBITORS OF FREE RADICAL INITIATED POLYMERIZATION OF ETHYLENICALLY UNSATURATED MONOMERS. THE POLYMERS CAN BE USED TO PRODUCE FILMS OR AS PROTECTIVE COATINGS.
