Abstract—The radical copolymerization of poly(ethylene glycol maleate) with acrylamide was performed for
the ﬁ rst time to obtain 3D cross-linked polymers. The inﬂ uence of temperature, pH of the medium, and organic
solvents on the behavior of the synthesized copolymers was studied. The possibility of obtaining nickel nanopar-
ticles in the bulk of the polymer gel for pyridine hydrogenation was demonstrated.
Active progress of basic research in the ﬁ eld of radical
copolymerization, allowing control of the properties,
structure, and molecular mass of the copolymers and the
reaction rate, makes it topical to search for new monomers
for preparing polymers with a wide spectrum of valuable
Unsaturated polyester resins are of much interest from
this viewpoint. They readily copolymerize with vinyl
monomers. Copolymerization of unsaturated polyester
resins was considered for the ﬁ rst time by Boenig .
The capability of polyester resins to copolymerize
with vinyl monomers, e.g., with styrene, was discovered
in the middle of the XX century .
Unsaturated polyester resins based on maleates and
fumarates, cured with vinyl monomers, exhibit speciﬁ c
physicochemical and physicomechanical properties
[1–4]. Therefore, the production of decorative ﬁ nishing
materials and structural items from polyester–styrene
copolymers is being actively developed today.
Copolymerization of unsaturated polyester resins with
acrylates has been studied previously [5–7], but data on
the related reactions with acrylamide are lacking.
The latest studies on copolymerization of unsaturated
polyester resins were published in the 1980s. They
mainly deal with the development of new formulations
for preparing structural materials based on styrene and
acrylates. On the other hand, 3D cross-linked copolymers
based on unsaturated polyester resins can be highly
effective polymeric supports for nanocatalysts based on
transition metals. Such compounds are stable and prevent
metal particles from aggregation and oxidation for a long
Here we report on a first study of the radical
copolymerization of poly(ethylene glycol maleate)
with acrylamide in solution to obtain 3D cross-linked
polymers and consider the possibility of using these
polymers as matrices for preparing catalysts based on
Poly(ethylene glycol maleate) (p-EGM) was prepared
by polycondensation of maleic anhydride with ethylene
glycol according to the standard procedure . The
reaction progress was monitored by determining the acid
number and the volume of the released water.
The molecular mass (MM) of p-EGM (2350 amu on
the average) was determined by the methods of light
scattering with a 2100 AN nephelometer (NACH) and
of gel permeation chromatography with an Agilent 1260
Inﬁ nity device.
