| Summary: | In this paper, we report that the compatibility of
polymer blends between linear low-density polyethylene (LLDPE) and cyclic
natural rubber (CNR) can be increased by the addition of oleic acid-grafted
linear low-density polyethylene. The research aims to investigate the effect of
LLDPE-g-OA compatibilizer in LLDPE/CNR blends on improving the mechanical
properties and characteristics of the blends. The LLDPE/CNR/LLDPE-g-OA blends
(compatible blends) were prepared by blending methods in the molten phase using
an internal mixer set at a temperature of 160oC with a rotation
speed of 100 rpm. The LLDPE pellets were inserted into it until melts and
followed with an addition of CNR and LLDPE-g-OA. The tensile strength test
results have shown an increase in mechanical properties after the addition of
the compatibilizer with a maximum content of 4 wt%. The difference in FTIR
spectra of compatible blends is indicated by the presence of C=C bonds from
CNR, which appear at 1654.9 cm-1, indicating the occurrence of physical
bonds in the blends. The existence of the LLDPE-g-OA compatibilizer has
increased the thermal stability of the polymer blends and changes in the
melting point temperature of 1240C. Compatible blends showed that
the surface morphology was smoother, and there were significant microstructural
changes compared to incompatible blends. |
