✦ Synopsis

The mechanical properties of three binary mixtures of incompatible polymers (LDPE/PP, LDPE/PS and LDPE/PVC) have been studied in the presence of potential solid phase dispersants. The results show that it is possible to achieve an acceptable level of toughness in the composite products for the re-use of the materials in demanding applications. It is suggested that the main factor necessary to achieve good impact resistance and elongation at break of the polymer is the presence of a rubbery interphase between the heterophases. Satisfactory tensile strength on the other hand depends more on the dispersant properties of the third component.
