In this article, the synthesis of Poly(ester-sulfone)s was
presented by a novel method with sodium formaldehyde sulfoxylate
and diacrylate monomer. The structures of samples were
identified by FT-IR, element analyzer, and 1H-NMR. The results
confirmed that the new preparation method of Poly(ester-sulfone)
s can be done directly and readily. The crystal morphology and
thermal properties of samples were investigated by the polarized
optical microscopy, X-ray diffraction, DSC, and TGA. The Poly(
ester-sulfone)s exhibited the morphology of ringed spherulites.
The incorporation of sulfone groups into the Poly(ester-sulfone)
s resulted in the increase of the melting point of polymers and
the decrease of thermal degradation temperature.The novel type
of Polyamide containing sulfone group were synthesized throug
direct polycondensation of diamines and diacrylic acid sulfones
which were prepared by the reaction of sodium formaldehyde
sulfoxylate with acrylic acid. It was interesting that the
properties of these polyamides differed from those of the
conventional ones. The withdrawing electron effect of the
sulfone group raised the reactivity of diacrylic acid sulfone
and then increased the reaction yield. The solubility and
thermal stability of polymers were lowered by the introduction
of sulfone group into them. From the above investigation, the
aliphatic poly(ester-sulfone)s can be used as resists in
microlithography because of the instability of them toward heat
and the sensitivity to high energy radiation.
