Phase Structure of Polylactide/Linear Low Density Polyethylene/Ethylene-Methyl Acrylate-Glycidyl Methacrylate Terpolymer Blends
摘要
Abstract
The blends of polylactide(PLA), linear low density polyethylene (LLDPE) and ethylene-methyl acrylate-glycidyl methacrylate terpolymer(EMAG) were prepared with EMAG as a compatibilizer. The PLA/LLDPE/EMAG blends were characterized by means of SEM, WAXD and DSC. The results show that the tendency of PLA to crystallize is reduced, and the domain sizes of LLDPE dispersed in PLA matrix decrease with the addition of EMAG, which indicates that the compatibility between PLA and LLDPE is improved by EMAG. The spreading coefficient calculations indicate that EMAG spreads on LLDPE extensively to encapsulate LLDPE completely. The elongation rate and Charpy impact strength of PLA/LLDPE/EMAG blends increase with increasing EMAG content. When m (PLA) : m( LLDPE) : m(EMAG) is 81 : 9 : 10, PLA/LLDPE/EMAG blend has elongation rate of 227% and Charpy impact strength of 32. 0 kJ/m2, relatively high strength and stiffness.关键词
