中文摘要	blends of linear low-density polyethylene (lldpe) with polystyrene (ps) and blends of lldpe with high-impact polystyrene (hips) were prepared through a reactive extrusion method. for increased compatibility of the two blending components, a lewis acid catalyst, aluminum chloride (alcl3), was adopted to initiate the friedel-crafts alkylation reaction between the blending components. spectra data from raman spectra of the lldpe/ps/alcl3 blends extracted with tetrahydrofuran verified that lldpe segments were grafted to the para position of the benzene rings of ps, and this confirmed the graft structure of the friedel-crafts reaction between the polyolefin and ps. because the in situ generated lldpe-g-ps and lldpe-g-hips copolymers acted as compatibilizers in the relative blending systems, the mechanical properties of the lldpe/ps and lldpe/hips blending systems were greatly improved. for example, after compatibilization, the izod impact strength of an lldpe/ps blend (80/20 w/w) was increased from 88.5 to 401.6 j/m, and its elongation at break increased from 370 to 790%. for an lldpe/hips (60/40 w/w) blend, its charpy impact strength was increased from 284.2 to 495.8 kj/m(2). scanning electron microscopy micrographs showed that the size of the domains decreased from 4-5 to less than 1 mum, depending on the content of added alcl3.
