A series of novel soluble aromatic polyamides with cyano side groups were synthesized by low temperature polycondensation of aromatic diamines with 2,6-bis(3-chloroformylphenoxy) benzonitrile in presence of N,N-dimethylacetamide as solvent and tertiary amines as absorbent of HCl.

Poly(aryl imino) containing biphenyl group was synthesized by the condensation polymerization of 4,4\'-Dibromobiphenyl and aromatic diamines via Palladium-catalyzed aryl amination reaction The structure of the polymers synthesized was characterized by means of FT-IR,1H-NMR spectroscopy and elemental analysis,and the testing results show a good agreement with the proposed structure.

Poly(imino ketone)-3(PIK-Ⅲ),a novel polymer of high performance,was synthesized via palladium-catalyzed polycondensation reaction using 1,4-bis-(4-bromobenzoyl)benzene and aromatic diamine as monomers.

Subsequently, 1a or 1b reacted with aromatic diamines 2a～2c to give bis(4-pyrrol-1'-ylphenyl)Y (Y=methane, ether or sulfone).

Bismaleimides(BMI),epoxy resins and aromatic diamines are used to prepre solventless epoxy adhesive.

A solid phase extraction combiantion with gas chromatography-mass spectrometry(SPE/GC-MS) was developed for the determination specific migration limitation of 24 primary aromatic amines(PAA) migrated from food contact plastic materials and articles.
