A new class of poly(amide-imide-urethane) thermoplastic elastomers based on two-step synthesis of 4,4@-methylene bis(4-phenylisocyanate) with di †erent polyols (PPG and PTMG) and trimellitic anhydride was synthesized. Both resulting polymers showed semicrystalline structures and were readily soluble
## Abstract Summary: Branched poly(arylene ether)s were prepared in an oligomeric A~2~ + B~3~ polymerization of phenol endcapped telechelic poly(arylene ether sulfone) oligomers as A~2~ and TFPPO as trifunctional monomer B~3~. The molar mass of the A~2~ oligomer significantly influenced the onset o
