摘要: Abstract In the present study, we have investigated morphology and thermal properties of blends low density polyethylene (PE) polyamide-6 (PA-6) with two poly(ethylene-graft-ethylene oxide)s (PE-PEO) as compatibilisers. Blends PE/PA-6 ratios between 70:30 30:70 copolymer contents 0 6% were prepared by melt mixing in a Brabender Plastograph. The was studied SEM. Addition PE-PEO2000 to decreased size dispersed phase domains significantly increased adhesion phases. addition PE-PEO750 did not any measurable effect on blend. At ratio 40:60, blend formed continuous 4% this improved phases significantly.
