RUM/3-59-10-14/16
Polyesters With Pyridine Nucleus in the Macromolecular Catena
phthalic pyridine polyesters and their copolyesters,
The analysis of these data shows that the presence
of the pyridine nucleus within the polyester macro-
molecule, has a-direct effect on the increase in
the number of solvents in which the respective
polymers are soluble. For various reasons a
number of polyesters cannot be used such as para-
pyridine 2,5 and all copolyesters of para-pyridine.
Terephthalic copolyesters with 5 - 10 % meta-
pyridine nuclei in the macromolecule can be qpun.
They have a melting temperature of 220 - 230uC
and a whitish color. Cold-stretched fibers were
obtained from these polymers. Synthetic fibers
based on polyethylene terephthalate might possibly
be utilizable after a total or partial elimination
of their disadvantages due to the fact that the
crystallinity of these copolyesters is a little
less and the basic nitrogen is present in the
Card 2/3 pyridine nucleus of the macromolecule. These
