Heterocyclic endo alicyclic end capped resins

Abstract

Abstract RESINS HAVING HIGH TEMPERATURE STABILITY CAN BE MADE BY CURING CHEMICALLY STABLE ALICYCLIC ENDO END CAPPED AROMATIC PREPOLYMERS. THE PREPOLYMERS CAN BE MADE FOR REACTING PROPER STOICHIOMETRIC AMOUNTS OF AN AROMATIC DICARBOXYLIC DERIVATIVE WITH A POLYFUNCTIONAL SUBSTITUTED AROMATIC AMINE, SUCH AS A TETRAAMINE, DITHIOLDIAMINE, OR A DIHYDROXYDIAMINE, AND AN END CAPPING COMPOUND HAVING THE FORMULA 1-Y2,2-Y3,3-Y4,4-Y5,5-Y6,5-Y7,6-(Z2-Z1-),6-Y1,1,4-(-X-)- CYCLOHEX-2-ENE WHEREIN Y1-Y6, INCLUSIVE, CAN BE HYDROGEN, HALOGEN, NITRO, ARYL, ALKYL, ALKYL ETHER, OR ALKARYL; X CAN BE CARBONYL, OXYGEN, SULFUR, METHYLENE, HALOGEN SUBSTITUTED METHYLENE, ALKYL SUBSITUTTED METHYLENE, OR ARYL SUBSITUTTED METHYLENE; Z1 CAN BE AN ARYLENE RADICAL OR AN ALKYLENE GROUP HAVING 0 TO 4 CARBON ATOMS; Z2 CAN BE AN ACID GROUP, AN ACID HALIDE, AN AMINE, OR AN ESTER GROUP; AND Y7 CAN BE HYDROGEN, HALOGEN, NITRO, ARYL, ALKYL, ALKYL ETHER, ALKARYL, OR AMINO IN A STABLE COMBINATION WITH Y6. THE END CAPPING COMPOUND CAN BE SYNTHESIZED BY REACTING A CYCLODIOLEFIN WITH AN OLEFINIC COMPOUND ACCORDING TO A DIELS-ALDER REACTION.
