the interaction of the external donor (propyltrimethoxysilane - ptms) with titanium-magnesium catalysts (tmcs) containing dibutylphthalate (dbp) as internal donor, which were prepared in different ways, was studied by chemical analysis and infrared diffuse reflectance spectroscopy (drifts). the chemical composition of the catalysts after their interaction with heptane solutions of ptms, ptms/al...

ABSTRACT Butadiene rubber (BR) is one of the most useful and second produced worldwide. Polymerization 1,3-butadiene (BD) a highly stereospecific reaction that offers wide variety BR with different microstructures influences fundamental properties rubber. Since first successful polymerization conjugated diene using Ziegler–Natta–based catalyst (TiCl4 or TiCl3 aluminum alkyls) in 1954, research ...

Polypropylene (PP) random copolymers are an important class of commercial materials that can be tuned for a wide range different applications. The structure–property relations mainly discussed in this article focusing on two major influencing factors, the catalyst system and type amount comonomer. Ziegler–Natta (ZN) systems still dominate production polypropylene todays sixth-generation ZN cata...
