Endo alicyclic end capped polyimidazopyrrolone
Abstract
Abstract 1-Y2,2-Y3,3-Y4,4-Y5,5-Y6,5-Y7,6-(Z2-Z1-),6-Y1,1,4-(-X-)- RESINS HAVING HIGH TEMPERATURE STABILITY CAN BE MADE BY CURING CHEMICALLY STABLE ALICYCLIC ENDO END CAPPED AROMATIC PREPOLYMERS. THE PERPOLYMERS CAN BE MADE BY REACTING PROPER STOICHIOMETRIC AMOUNTS OF TETRAACIDS OR DERIVATIVES WITH AN AROMATIC TETRAAMINE, AND AN END CAPPING COMPOUND HAVING THE FORMULA 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 SUBSTITUTED METHYLENE, OR ARYL SUBSTITUTED METHYLENE; Z1 CAN BE AN ARYLENE OR AN ALKYLENE GROUP HAVING 0 TO 1 CARBON ATOMS; Z2 CAN BE AN ISOCYANATE RADICAL OR AN AMINE RADICAL; AND Y7 CAN BE AN ISOCYANATE RADICAL OR AMINO IN A STABLE COMBINATION WITH Y6. THE END CAPPING COMPOUND CAN BE SYNTHESIZED BY REACTING A CYCLO DIOLEFIN WITH AN OLEFINIC COMPOUND ACCORDING TO A DIELS-ALDER REACTION.
