摘要

The resin solution of NA capped‘PMR' type polyamide-imide was prepared from bicyclo [2.2.1]-hept-5-ene-2

3-dicarboxylic acid ethyl ester

4-trimellitic acid-2-(or-1-) ethyl ester and 4

4'-methylenedianiline in ethanol. This resin solution is specially suitable for the preparation of compo-sites. The fiexural strength of the glass cloth reinforced plastics was 6000--7000 kg/cm2 (RM) and4000--kg/cm2 (260°--300℃)

respectively. The result of isothermal aging for 800 hours in-dicated that this composite can be used at 260℃.The mechanism of the formation of polyamideimide was discussed by using appropriate model compounds.
