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 (ppI 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.
