Abstract—The interaction of a number of phenol compounds with silica ﬁ ller of polymer compositions (highly
dispersed amorphous silicas) was studied by the pyrolysis gas chromatography mass spectrometry. AP-UBS
modiﬁ er was tested in protector, facing, and breaker rubber mixtures.
Increasing requirements to consumer’s quality, per-
formance, and environmental safety of products made
of thermoplastic elastomers (TPEs) necessitate the de-
velopment and introduction of new efﬁ cient modiﬁ ers
for polymer compositions.
Phenolic compounds (resorcinol, 5-methylresorcinol)
in combination with hexamethylenetetramine (urotropin),
widely used as modiﬁ ers, have reasonably high effective-
ness, but suffer from some known drawbacks .
It was shown previously  that AP-U resin obtained
by acid-catalyzed alkenylation of 5-methylresorcin with
1,3-pentadiene, while introduced into TPE compositions
jointly with silica ﬁ llers, considerably enhances strength
of ready items. In this case, the synergetic effect arises
from the interaction of hydroxyl groups of the resin with
a silica ﬁ ller (see the scheme).
The study is concerned with the interaction of AP-U
resin with silica ﬁ ller (white black). The estimate of the in-
teraction of AP-U with BS-100 showed that in the system
BS-100-SKEPT-70 rubber and in a ternary system BS-
100-SKEPT-70-low-density polyethylene (PVD 15803-
020), AP-U serves as rheological additive increasing the
interaction intensity, i. e., gives the synergetic effect .
Therefore, it was of interest to estimate the efﬁ ciency of
AP-U interaction with BS-100 and other silica ﬁ llers from
the data on the pyrolysis products.
The systems were heated at 450°С in a flow of
an inert gas (helium) in a pyrolytic packing of a GCMS
QP 2010 Plus gas chromatography-mass spectrometer
(Shimadzu). The pyrolysis products were separated on
a 30-m quartz capillary column with a nonpolar liquid
phase, poly(methyl-5% phenyl)siloxane. In identiﬁ ca-
tion of the chromatographic peaks, we used along with
the mass spectra the Electron Ionization Library (NIST
Retention Index Database).
