heal.abstract	The role of polyolefin elastomers as compatibilizers in Low Density P olyethylene/Polypropylene (LDPE/PP) blends, in the presence of di-cumyl peroxide (DCP) has been studied. Mixtures of 90/10 LDPE/PP ratio, were prepared in a Brabender plasticorder and tested for their mechanical properties and calorimetric response. Then the elastomers ethylene-propylene-diene copolymer (EPDM) and polybutadiene (BR) were added, alone or together with 0.2% DCP at concentrations up to 2%. The mixing torque and gel content of the above products were recorded as a function of the blend consistency. Also, the mechanical properties of specimens were measured as an additional evidence to explore the capabilities of these additives to promote compatibility of the blend components. It was found that EPDM and BR can be easily incorporated into polyolefin blends and appear suitable as potential compatibilizers for those materials, probably acting within the PP phase. Both elastomers result in an increase of strength and modulus, the BR having more enhanced effect. The latter gives low elongation, which allows its use in applications where high tensile properties are desired and flexural behavior is not critical.	en
