the solid state rheological investigation of core-shell impact modifier nanoparticles efficacy: 3-d networking

In this research work, the impact modifications of pvc/san blends containing g-abs or mbs core-shell nanoparticles were scrutinized and correlated with the solid state rheological properties of system. izod impact and rheological tests were conducted to evaluate the brittle-ductile transition (bdt), about 10 wt. %, of alloys as well as the efficacies of nanoparticles. a pervasive 3-d network of mbs in pvc and g-abs in pvc and/or san altered the failure mechanism from crazing to shear yielding induced by cavitation, respectively. it amplified the matrix toughness as much as 9 times. the estimation of blend system toughness based on its rheological flow is under development.
