Thermosetting alicyclic endo end capped resins

Abstract

Abstract RESINS HAVING GOOD THERMAL AND CHEMICAL STABILITY ARE MADE BY CURING CHEMICALLY STABLE ALICYCLIC ENDO END CAPPED COMPOUNDS HAVING OXY OR SULFONE SUBSTITUENTS. THE PREPOLYMERS ARE MADE BY REACTING PROPER STOICHIOMETRIC AMOUNTS OF AN AROMATIC SULFONE OR AN AROMATIC ETHER CONTAINING AT LEAST TWO FUNCTIONAL SUBSTITUENTS WHEREIN THE AROMATIC RING GENERALLY FUNCTIONS AS BOTH THE ELECTRON DONOR OR ACCEPTOR, DEPENDING UPON THE NATURE OF THE SUBSTITUENT USED TO FORM THE LINKAGE, AND END CAPPING WITH AN ALICYCLIC ENDO COMPOUND HAVING THE FORMULA 1,4-(-X-),1-Y2,2-Y3,3-Y4,4-Y5,5-Y6,5-Y7,6-(Z2-Z1-),6-Y1- CYCLOHEX-2-ENE WHEREIN Y1-Y7, INCLUSIVE, CAN BE HYDROGEN, HALOGEN, NITRO, ARYL, ALKYL, ALKYL ETHER, OR ALKYARYL; X CAN BE CARBONYL, OXYGEN, SULFUR, METHYLENE, HALOGEN SUBSTITUTED METHYLENE, ALKYL SUBSTITUTED METHYENE, OR ARYL SUBSTITUTED METHYLENE; Z1 CAN BE AN ARYLENE RADICAL OR AN ALKYLENE GROUP HAVING 0 TO 4 CARBON ATOMS; AND Z2 CAN BE A HALIDE OR A HYDROXYL GROUP. THE END CAPPING COMPOUNDS ARE SYNTHESIZED BY REACTING A CYCLODIOLEFIN WITH AN OLEFINIC COMPOUND ACCORDING TO A DIELS-ALDER REACTION.
