Abstract EN
In this work the polyimides were prepared as thermally stable polymers by different ways.
In order to perform the above mentioned project the following outlines are classified: 1.
A- Preparation of a number of new N-substituted maieamic acids.
B- Dehydration of above maieamic acids to their corresponding N- substituled maleimides.
C- Polymerization of all the new maleimide monomers.
2.
A- Preparation of N-substituted maleimides from reaction of maleimide with alkyl halides.
B- Polymerization of N-alkyl substituted maleimide monomers.
3.
A- Polymerization of maleimide compound free radically by using AIBN as initiator.
B- Substitution of polyimide by using different alkyl halides.
All the prepared monomers and polymers were characterized by IR, UV spectra, elemental analysis, thermal analysis and chemical reaction.
Physical‘properties and the viscosities for ail polyimides were determined by using DMF as a solvent.
We concluded; from all the results of different ways that the 3K< method gave the best result than the lml and the lM methods, it gave higher molecular weight and higher softening point.
