Abstract
Polyimides are made by reacting approximately equimolar proportions of at least one diamine having the structural formula H2N-R1-NH2 where R1 is a divalent radical containing at least two carbon atoms, the two amino groups of said diamine each attached to separate carbon atoms of said divalent radical; with at least one tetracarboxylic acid dianhydride having the structural formula <FORM:0903271/IV(a)/1> where R is a tetravalent radical containing at least 2 carbon atoms; no more than 2 carbonyl groups of said dianhydride attached to any one carbon atom of said tetravalent radical; in an organic solvent for at least one reactant whose functional groups do not react with either of the reactants to a greater extent than the reactants do with each other, under substantially anhydrous conditions while maintaining the temperature throughout the reaction below 60 DEG C. to provide a polymer containing at least 50% polyamide-acid having a viscosity measured at 30 DEG C. in a 0,5% by weight solution, of at least 0,1 and reacting the polymer with an aliphatic acid anhydride or carbodiimide to convert the polyamide-acid to a polyimide. Many suitable diamines are specified, examples being 4:41-diaminodiphenyl propane, m-xylylene diamine and 1:12-diaminooctadecane. Specified dianhydrides are pyromellitic, 2:3:6:7-naphthalene tetracarboxylic, 1:2:5:6-naphthalene tetracarboxylic, 2:21:3:31-diphenyl tetracarboxylic, 2:2-bis(3:4-dicarboxyphenyl) propane, bis(3:4-dicarboxyphenyl) sulphone, perylene-3:4:9:10-tetracarboxylic, bis(3:4-dicarboxyphenyl) ether and ethylene tetracarboxylic acid dianhydride. Specified solvents are N:N-dimethyl formamide, N:N-dimethyl acetamide, N:N-diethyl formamide, N:N-diethyl acetamide, N:N-dimethylmethoxy acetamide, N-methyl caprolactam, dimethyl sulphoxide, N-methyl-2-pyrrolidone, tetramethylene urea, pyridine, dimethyl sulphone, formamide, N-methyl formamide or N-acetyl pyrrolidone alone or in admixture with benzene, benzonitrile, dioxane, butyrolactone, xylene, toluene or cyclohexane. Specified aliphatic acid anhydrides are acetic, propionic, butyric and valeric anhydride. Many examples are given. Specification 898,651 is referred to.
