Klein, K. P.; Reimschuessel, H. K. published the artcile< Polyimide from 4-carboxy-2-piperidone-poly[1,3-(2,6-dioxopiperidinediyl)ethylene]>, Electric Literature of 25504-47-6, the main research area is polyimide carboxypiperidone; piperidone carboxy polyimide; hydrocyanation itaconate ester; cyanomethylsuccinate dimethyl hydrogenation.
A polyimide (I) [84128-67-6] soluble in HCO2H, m-cresol, CF3CH2OH, and H2SO4 was prepared by heating 4-carboxy-2-piperidone (II) [24537-50-6] at 220-235°. I had Mark-Houwink constants K and α 4.2 × 10-4 and 0.647, resp., in m-cresol and glass transition temperature 130-135°. II was prepared by hydrocyanation of di-Me itaconate [617-52-7], reduction-cyclization of the di-Me (cyanomethyl)succinate [24537-51-7] to 4-(carbomethoxy)-2-piperidone [25504-47-6], and hydrolysis.
Macromolecular Syntheses published new progress about Polyimides Role: SPN (Synthetic Preparation), PREP (Preparation). 25504-47-6 belongs to class piperidines, and the molecular formula is C7H11NO3, Electric Literature of 25504-47-6.
