SUMMARY
This
paper
presents
the results relating 10 the influence
uf
santopren (SAN) content to the
properties
of
polymer blend based on natural rubber (NRI and polypropvlen
(pp
I with the
presence
of
peroxide
inflator. The
properties
of
polymer
blend
are best when the content
of
SAN
is
10%. The initial tensile strength is 19.27 MPu, after the
accelerating
weather
fest if
remained
above 86%. The thermal gravimetric analysis (TCA) showed that the polymer blend with
f()°/"SAN was resistant up to 25(J'C. This polymer would be degraded more slowly than that
of
the
polymer blend without SAN.
