Graft copolymer (methacrylate-butadiene-styrene, MBS) supplied by Thai Plastic and
Chemicals Co. Ltd. was characterized by Fourier transform infrared (FTIR) spectroscopy. The
FTIR spectrum of this graft copolymer (Figure 1) shows several characteristic peaks attributed to
C=C stretching of butadiene, C=O stretching of ester groups of methyl methacrylate, and the
monosubstituted benzene ring of styrene atwavenumbers of 1640, 1732, and 698 cm

,
respectively. This provides evidence that the graft copolymer was formed during the grafting of
styrene and methyl methacrylate grafted onto the butadiene backbone.
incorporation of EPDM, the blends possessed better stable tensile strength against thermal and
weathering aging than NR rich blends. The effectof methyl methacrylate-butadiene-styrene (MBS)
as a compatibilizer in a 50/50 NR/EPDM blend on the blend properties has been studied in detail.
The addition of the compatibilizer improved the compatibility of the NR/EPDM blends
