Claims
- 1. A polymer consisting essentially of a recurring unit represented by formula: ##STR17## wherein Z is selected from the group consisting of: ##STR18## and R is a tetra-valent radical selected from the group consisting of an aliphatic radical having two or more carbon atoms, a cycloaliphatic radical, a monoaromatic radical and a condensed polyaromatic radical wherein the aromatic radicals are mutually connected with a bond or a crosslinking function, and at least one recurring unit is represented by formula: ##STR19## wherein Y is a radical selected from the group consisting of a divalent hydrocarbon having 1 to 10 carbon atoms, hexafluorinated isopropylidene, carbonyl, thio, sulfinyl, sulfonyl and oxide, and Z has the above-stated meaning, which is obtained by reacting a mixture of a diamine represented by formula: ##STR20## and at least one diamine represented by formula: ##STR21## wherein Y has the above-stated meaning, with tetracarboxylic acid dianhydride represented by formula: ##STR22## wherein R has the above-stated meaning.
- 2. The polymer of claim 1 wherein said diamine represented by formula: ##STR23## is selected from the group consisting of bis[4-(3-aminophenoxy)phenyl]methane, 1,1-bis[4-(3-aminophenoxy)phenyl]ethane, 1,2-bis[4-(3-aminophenoxy)phenyl]ethane, 2,2-bis[4-(3-aminophenoxy)phenyl]propane, 2,2-bis[4-(3-aminophenoxy)phenyl]butane, 2,2-bis[4-(3-aminophenoxy)phenyl]-1,1,1,3,3,3-hexafluoropropane, bis[4-(3-aminophenoxy)phenyl]ketone, bis[4-(3-aminophenoxy)phenyl]sulfide, bis[4-(3-aminophenoxy)phenyl]sulfoxide, bis[4-(3-aminophenoxy)phenyl]sulfone and bis[4-(3-aminophenoxy)phenyl]ether.
- 3. The polymer of claim 1 wherein Z is: ##STR24##
- 4. The polymer of claim 1 wherein Z is: ##STR25## and R is a tetravalent radical of formula: ##STR26##
- 5. A polymer consisting essentially of two or more recurring units which is represented by formula: ##STR27## wherein Z is selected from the group consisting of ##STR28## and R is a tetravalent radical selected from the group consisting of an aliphatic radical having 2 and more carbons, a cycloaliphatic radical, a monoaromatic radical, and a condensed polyaromatic radical wherein the aromatic radicals are mutually connected with a bond or a crosslinking function, and each Z in the units differ from one another.
- 6. A high-temperature stable adhesive of a polymer consisting essentially of a recurring unit of formula: ##STR29## wherein Z is selected from the group consisting of: ##STR30## and R is a tetra-valent radical selected from the group consisting of an aliphatic radical having two or more carbons, a cycloaliphatic radical, a monoaromatic radical and a condensed polyaromatic radical wherein the aromatic radicals are mutually connected with a bond or a crosslinking function, and at least one recurring unit is represented by formula: ##STR31## wherein Y is a radical selected from the group consisting of a divalent hydrocarbon having 1 to 10 carbon atoms, hexafluorinated isopropylidene, carbonyl, thio, sulfinyl, sulfonyl, and oxide, and Z has the above-stated meaning, which is obtained by reacting a mixture of a diamine represented by formula: ##STR32## and at least one diamine represented by formula: ##STR33## wherein Y has the above-stated meaning, with tetracarboxylic acid dianhydride represented by formula: ##STR34## wherein R has the above-stated meaning.
- 7. The high-temperature adhesive of claim 6 wherein Z is: ##STR35##
- 8. The high temperature adhesive of claim 6 wherein Z is: ##STR36## and R is a tetravalent radical of formula: ##STR37##
- 9. A high temperature adhesive of a polymer consisting essentially of two or more recurring units which is represented by formula: ##STR38## wherein Z is selected from the group consisting of: ##STR39## and R is a tetra-valent radical selected from the group consisting of an aliphatic radical having 2 and more carbons, a cycloaliphatic radical, a monoaromatic radical and a condensed polyaromatic radical wherein the aromatic radicals are mutually connected with a bond or a crosslinking function, and each Z in the units differ from one another.
