Abstract
The present invention relates to new polyetherimideimides having imideimide group with the following structural formula(I) and inherent viscosity of 0.27.about.0.71 dl/g, which can be made by effecting reaction between an aromatic bis(ether anhydride) and an organic diamine or an aromatic bis(nitro imideimide) and a metal salt of diol. ##STR1## Wherein, R is ##STR2##
Claims5
A polyetherimide-imide resin characterized by having imide-imide group with the following structural formula (I) and inherent viscosity (.eta.inh) of 0.27.about.0.71 dl/g ##STR9## Wherein R is selected from group of ##STR10## Ar is selected from alkyl group or phenyl derivatives with 6 to 12 carbons, and p is an integral number between 10 and 1000.
