摘要：
Taking random copolymer poly(styrene-co-methyl acrylate) (PSMA) (nSt:nMA=75:25) as compatibilizer, we conducted the melt blending of the polylactide (PLA) and the triblock copolymer styrene-butadiene-styrene (SBS) on a twin-screw extruder, and explored the impact of PSMA content on the compatibility of PLA/SBS (mPLA:mSBS=90:10) blends. Furthermore, the scanning electron microscope, universal tensile testing machine, differential scanning calorimeter and rotary rheometer were employed to characterize the microstructure, mechanical properties, thermal properties and rheological properties of PLA/SBS blends. It could be observed by SEM that adding 1wt% PSMA enabled uniform dispersion of SBS in PLA/SBS blends and enhanced the interfacial adhesion of PLA/SBS blends as well. Meanwhile, the elongation and impact strength of PLA/SBS blends with 1wt% PSMA were 7.1 and 2.3 times of those of pure PLA, respectively. Besides, DSC and rheological results indicated an improved compatibility of PLA and SBS by the addition of PSMA. © 2019, Materials Review Magazine. All right reserved.
