that at 136.3C the polycondensation -of ILA and HU partly proceeded in the melt
phase, the actual malting point of the ztixture being 172-173C, while that of its
constituents is 193-194C and 1950. , For PA and PAP?, the homopolymors of which are
practically not-fusible, the reaction ~ coeds via melt at a temperature exceeding
-235c, and for HDA and DDHTA at over ("0. The copolycondensation process for HDA
and HDIP in a ltl ratio proceeds at 1690 in the solid phase. and. having reached
62% of its total potential, it practica3ly stops there. It is assuned that only
HDA reacts at this point, which is-confUmed by analysis of the resulting poly-
condensate. The.canposition of,the obtained polyamides was studied by means,of
chromatography, and their solubility in'various solvents was investigated. It was
found that the W copolycondensation:product of PA and PAPP was soluble in tri-
cresol, while none of the constituent hqxopolymers were. The chromatographio in-
vestigation of the.copolycondenv-tion p;oduats revealed their structure as that of
copolymers with a statistic distribution. of monomeric units. This was established
*for the AA and ADA as well as HDA and DDktA oopolycondensation products. It is
iconcluded that the reaction under-inve3tigation yields a true polyamide and not a
mixture of homopolyamides. Orig. arU his:_ 5 charts.
