✦ Synopsis

The effect of 12 different potential compatibilizing agents on the interfacial tension of polyethylene (PE) and polyethylene terephthalate (PET) is described. A wide range of compatibilizing agents based upon ethylene and a second comonomer were devised and used. They were divided into three categories. The first category (I) includes block polymers. The second category (11) includes random copolymers. The third category (111) includes reactive copolymers that should form graft copolymers during mixing with PET. The addition of various potential compatibilizing agents to the PE/PET binary system results in lowered interfacial tension. The efficiency of the different compatibilizing agents in reducing the interfacial tension is discussed.

The breaking thread and the sessile drop methods have been used to evaluate the interfacial tension between a polypropylene (PP) and a polyethylene-terephthalate (PET). An excellent correlation was found between the two. The breaking thread technique was then used to evaluate the interfacial tension

Blends of polyethylene terephthalate (PET) and polypropylene (PP) at compositions 20/80 and 80/20 were modified with three different styrene-ethylene/butylene-styrene (SEBS) triblock copolymers with the aim of improving the compatibility and in particular the toughness of the blends. The compatibili
