ABSTRACT:
Diamines having a 1,1,3-trimethylphenylindane dicarboxylic moiety linked on both sides to phenylene diamine by an amide bond (PIDA diamines) are disclosed. By reacting these diamines with aromatic difunctional acid derivatives, amorphous polymers having high glass transition temperatures (Tg) can be prepared. If aliphatic diacid derivatives are used the resulting polymers have a lower Tg, but have the advantage of melt-processability. The PIDA-diamines can also be used in the preparation of polyimides, being reacted either with tri- or tetracarboxylic anhydrides or with imide group-containing acid derivatives.
