Abstract-A polymer system based on KORS copolymer and RS solvent prepared from wastes from
production of butyl alcohols was studied. The RS solvent can replace butyl acetate and xylene, with
improvement of the physicomechanical properties of the coatings obtained.
Polymeric materials are multicomponent systems
based, in the overwhelming majority of cases, on
solutions in organic solvents. The preparation con-
ditions and quality of polymeric coatings largely
depend on propeties of the starting materials, which
should meet the following requirements: possibility
of distribution on the substrate surface as a thin
layer, capability for film formation, and formation
of coatings with the desired properties .
Production and use of polymeric materials in-
volves consumption of enormous amounts of organ-
ic solvents . Virtually the whole amount of them
is irretrievably lost in the course of coating applica-
tion, giving rise to environmental and economical
problems. Powder and water-dispersible polymeric
coatings used today solve these problems, but pow-
der polymeric materials are unsuitable for domestic
use because they require special equipment for
application, and their decorative properties are poor.
Water-dispersible polymeric formulations can be
efficiently applied only in the warm period of year,
and water-soluble surfactants present in them reduce
the protective properties of the coatings. Therefore,
one of the main avenues of the progress of the var-
nish-and-paint industry today is the development of
polymeric formulations with decreased content of
organic solvents, search for new solvents of low
toxicity and for new sources of raw materials, and
development of new processes for their production
The dissolution of film-forming substances is
determined by the chemical composition and struc-
ture of the film-forming agent and by the chemical
nature and thermodynamic characteristics of the
solvents used [6, 7].
RS solvent can be prepared from wastes from
production of butyl alcohols . Its composition was
determined by functional analysis and gas3liquid
chromatography. The composition and characteris-
tics of major components of RS solvent are given in
Table 1. The main component is isobutyl acetate
used in the formulations instead of butyl acetate and
cyclohexanone. The content of isobutyl acetate in
RS solvent reaches in some batches 75 wt %.
Formic and acetic acid esters entering into the
composition of RS solvent dissolve cellulose esters,
chlorinated rubber, vinyl polymers, and carbinol and
other resins; they are well miscible with many solv-
ents used in production of nitrocellulose varnish-
and-paint materials (VPMs) .
Isomers of butyl alcohols, whose content in the
solvent reaches 4.5 wt %, in a mixture with ethanol
are used for dissolving urea3formaldehyde oligomers
and polyvinylbutyral, and in a mixture with xylene,
for dissolving polyacrylates. They are added to the
majority of mixed solvents to enhance their solvency,
improve the adhesion of coatings owing to a de-
crease in the surface tension, prevent the films from
becoming turbid or white, and facilitate pouring of
lacquers and enamels by decreasing their viscosity.
RS solvent contains large amounts of butyl eth-
ers, mainly of dibutyl ether. Butyl ethers are used as
solvents for certain film-forming agents , mainly
