A new class of poly(amide-imide-urethane) thermoplastic elastomers based on two-step synthesis of 4,4@-methylene bis(4-phenylisocyanate) with di β erent polyols (PPG and PTMG) and trimellitic anhydride was synthesized. Both resulting polymers showed semicrystalline structures and were readily soluble

Novel poly(amide imide)s having inherent viscosities in the range 0.89-1.56 dL/g were prepared by the method of low temperature polycondensation in solution of N,N-dimethylacetamide (DMA) from aromatic diamines and a new monomer: N-[4"-(chloroformylphenyl) -4'-iminobenzoyl] trimellitimide chloride.
## Abstract Poly(amide imide)βepoxysilane (coupling agent) composites were reacted with silica, a condensation product of tetraethylorthosilicate (TEOS), by a solβgel process and were then cast into films. After this procedure, the chemical characteristics and mechanical and thermal properties were
