From the result, it could be found that the grafting degree and the molecular weight of SAN copolymers decreased with the TDDM content.

Effect of TDDM Content on the Morphology of CPVC/ABS Blends
2, it could be found that the dispersion of ABS domains all performed uniform dispersion, which mean that the TDDM could not obviously alter the morphology of CPVC/ABS blends.
Figure 4 shows tan [delta] curves of CPVC/ABS blends of different TDDM content in ABS.
Figure 5 shows the storage modulus of the CPVC/ABS blends on temperature of different TDDM content tested by DMA.
Figure 6 showed the notched impact strength and the tensile strength of the CPVC/ABS blends as function of the TDDM content.
Figure 7 displayed the elongation of the CPVC/ABS blends at break as function of the TDDM con-tent.
DMA revealed that the increasing of TDDM content could enhance the compatibility between CPVC and ABS.
