Abstract—Phosphorylated methacrylates were prepared by reaction of butylphosphoric acids and their salts
with glycidyl and β-chloroethyl methacrylates. The modifying properties of these substances toward epoxy–4,4'-
isopropylidenediphenol resins ED-16 and ED-20 were examined. The physicochemical characteristics and heat
resistance of the composites obtained were studied in relation to the structure of methacrylates, curing agent used,
formulation, and curing conditions.
Epoxy resins are widely used in building industry,
aircraft construction, and ship building, i.e., in industries
where the strength, hardness, and light weight of
materials are of particular importance [1, 2]. However,
the problem of developing composite materials of
decreased combustibility remains topical. The main
line of research in this ﬁ eld is associated with the use
of ﬁ re retardants [3–6]. The assortment of ﬁ re retardants
is steadily expanding [7, 8]. However, the majority of
problems related to ﬁ re protection, environmental safety,
and comprehensive improvement of properties are not
One of promising modification procedures is
preparation of compounds of the interpenetrating polymer
network (IPN) type. Phosphorylated methacrylates
and dienes are highly reactive in joint polymerization.
Various phosphorus- and halogen-containing oligoether
acrylates are known [9, 10]. These substances are used for
preparing ﬁ re-resistant composite polymeric materials. Of
considerable interest are derivatives of phosphorus acids
with two and more polymerization-capable (meth)acrylic
groups. They can be prepared by efﬁ cient procedures from
commercial raw material and form a three-dimensional
structure on curing.
Here we report on synthesis of new phosphorylated
methacrylates and on their modifying properties.
