Abstract

The present paper is aimed to evaluate the efficiency of two masterbatches, i.e., EBAGMALDPE MB1 and EBAGMAPET MB2 with 5050 ww composition, prepared by melt mixing and used as new compatibilizers for blends of LDPEPET. The morphology, the mechanical and the thermal properties of LDPEPETMB1 and LDPEPETMB2 ternary blends have been investigated. Morphological investigation by SEM of LDPEPETMB1 ternary blends showed a finer dispersion of PET in LDPE matrix with a better interfacial adhesion compared to those of both LDPEPETMB2 and binary LDPEPET blends. The results also indicated a substantial improvement in both elongation at break and impact strength, while the Youngs modulus decreased. Moreover, the thermal properties showed a decrease of the crystallization phenomena of PET in LDPEPETMB1 blend, thus confirming the good dispersion of PET particles into the continuous phase of LDPE matrix, leading to the conclusion that MB1 could be an efficient compatibilizer for LDPEPET system.

14. Melt Mixing of Ethylene/Butyl Acrylate/Glycidyl Methacrylate Terpolymers with LDPE and PET

Abstract

The chemical modification by meltmixing of an EBAGMA terpolymer with LDPE and PET was investigated with the aim to use these EBAGMALDPE and EBAGMAPET blends in equal weight quantities as compatibilizer master batches to improve the compatibility of the LDPEPET system. It is shown that when the EBAGMA terpolymer is melt blended with LDPE, almost 40 of the initial amount of EBAGMA is linked to the LDPE backbone. In contrast, in the case of EBAGMAPET, FTIR spectra indicate the total reactivity between the two components through the reaction of the epoxy group of EBAGMA with the PET terminal groups. SEM analysis shows that both master batches present two wellinterconnected phases.
