摘要：
In this paper, Janus hybrid particles with rubber brushes have been first fabricated by successively grafting polybutadiene chains onto polydivinylbenzene (PDVB) side and polyisoprene chains onto SiO2 side in the case of SiO2@PDVB Janus particles as the template. The weight grafting ratios (G(r)) of polybutadiene (PBd) and polyisoprene (PI) brushes were determined as 19.4 and 24.8 wt %, respectively. Such Janus hybrid particles contribute to not only the retardation of phase separation but also the kinetically trapped bicontinuous phase morphology in rubber blends. The interface jamming of these Janus particles supports their promising applications as compatibilizers in polymer blends.
