Abstract

The aim of this work was to compare the effects of compatibilisation with a pre-fabricated additive and the in-situ generation of a similar additive in the melt for LDPE-PA6-blends and to investigate the effect of mixing protocol (i.e. compounding vs. dry-blending) of the prefabricated additive on the resulting properties of reprocessed LDPE-PA6 films. We found, that it is possible to compatibilize LDPEPA6-blends via the addition of maleic anhydride based compatibilizers, regardless of fabrication approach. This effect can be seen from the morphology of the samples as well as from mechanical properties. Also, the reprocessing of films from LDPE and PA6 with reasonable properties is possible when adding a compatibilizer. The best, i.e. the most balanced properties can be found when the compatibilizer is melt compounded, as this gives the best distribution. These results show that it is possible to reuse multilayer materials when considering the blend components and properly selecting a compatibilizer.
