Abstract:
ETHYLIDENEBICYCLOPHETENE IS PRODUCED BY THE CATALYTIC ISOMERIZATION OF VINYLBICYCLOHEPTENE AT ELEVATED TEMPERATURES. THE CATALYSTS ARE THE COMPLEX COMPOSITIONS OBTAINED BY THE REDUCTION OF THE SALTS OF THE TRANSITION METALS COBALT AND IRON WITH HYDROCARBYLALUMINUM COMPOUNDS, AND THE CARBONYL COMPOUNDS OF SAID TRANSITION METALS. ETHYLIDENEBICYCLOHEPTENE IS A KNOWN COMPOUND USEFUL AS A COMONOMER IN THE PRODUCTION OF ETHYLENEPROPYLENE TERPOLYMERS.
Abstract:
The disclosure of this application is directed to unsaturated polyesters which are the condensation reaction products of a mixture of an unsaturated dicarboxylic acid or anhydride thereof, ethylene glycol and diethylene glycol; and to compositions based thereon which have particular utility in sheet molding and bulk molding applications to form thermoset articles of desired configuration.
