Vp. Privalko et al., THE CHARACTERISTICS OF CARDO POLY(AMIDE-I MIDE) IN SOLUTION AND BLOCK, Vysokomolekularnye soedinenia. Seria A, 37(1), 1995, pp. 119-126
The characteristics of cardo poly(amide-imide) based on dichloroanhydr
ide of trimelliteimido-N-p-benzoic acid and anilinefluorene were studi
ed in solution and in block. It was shown that in the range of low con
centration of the poly(amide-imide) in solution (<12%) the structure o
f solvent is disordered. Further dilution of semidiluted solutions is
exothermic due to formation of solvate shells around macromolecules. I
n block, the polymer studied is amorphous and has the glass transition
temperature 670 K.
