Abstract
New tetracarbonyl compounds of the formula ##STR1## where R is a hydrogen atom, an alkyl radical or an aryl radical. The invention also contemplates the thermostable polymers obtained by reacting an aromatic tetra-amine with at least one of the above tetracarbonyl compounds.
Claims6
A composition consisting essentially of a mixture of both 4,4'- and 4',4"-disubstituted metaterphenyl derivatives of the formulae:
- ##STR11## in which R' is methyl, chloromethyl, bromomethyl, dichloromethyl, dibromomethyl, ethyl, benzyl, phenylchloromethyl, or phenyl-dichloromethyl or dibromomethyl.
A 4,4'-disubstituted meta-terphenyl derivative of the general formula ##STR12## in which R' is methyl, chloromethyl, bromomethyl, dichloromethyl, dibromomethyl, ethyl, benzyl, phenylchloromethyl, or phenyl-dichloromethyl or dibromomethyl.
A 4',4" di-substituted meta-terphenyl derivative of the general formula ##STR13## in which R' is methyl, chloromethyl, bromomethyl, dichloromethyl, dibromomethyl, ethyl, benzyl, phenylchloromethyl, or phenyl-dichloromethyl or dibromomethyl.
