英文摘要Pb-g-mma core-shell impact modifiers were synthesized by seed emulsion polymerization and impact-modified pmma/pvc blends were prepared by melt blending pmma, pvc and pb-g-mma at 160 degrees c. the pb-g-mma particles were dispersed uniformly in the pmma/pvc matrix. pmma/pvc blends were prepared in the blend ratio from 100/0 to 0/100 and the rubber content was kept 16% in all the compositions. the effects of matrix composition on the mechanical properties and morphology of the blends were studied. it was found that when the matrix was a pmma-rich system, the sample broke in a brittle mode and crazing of the matrix was the main mechanisms of deformation. when the matrix was a pvc-rich system, the sample broke in a ductile mode and the main deformation mechanisms were cavitation of the particle and shear yielding of the matrix. there existed a transition from crazing to shear yielding in the rubber-modified pmma/pvc blend as the matrix composition varied.
