SUMMARY
Thanks to the structure properties, liquid natura! rubber (LNR) was used by several authors
as compatibili:er
for
polvrner blends based on lite natural rubber. This paper gave an orervicw
about the influence
of
the componbilizer
TIl
I
LNR
with the end Ol-i-groups
0/1
the morphology
and
properties
of
the research blend systems. The research results showed that THJ with the
molecular weight
of
8.500
had the best compatible effect
jar
the blends
NRIP! ·.
NRISBR and
NRiNBR. This cornpatibilizer
I'HI
was good
for
the blends the
components
of
which had the tittle
polarity difference like NRISBR. The phase
morphology
showed
a
good
component
dispersion.
The
mechanical
and
technical properties
of
the
polymer
blends were significantly
improved
by
/Ising this
companbili:rr.
