Compatibilization of polypropylene–polyethylene blends
Homopolymer PP was combined with PE of varying comonomer level. In addition to the effect of including compatibilizer, the effect of blend ratio and viscosity ratio is discussed. It was found that very fine dispersions could be obtained when including the compatibilizing polymer for all studied systems. The blend rheology was compared with ...

Because both PE and PP have high average M W (4000 and 250 000 g mol −1, respectively) and large average chain length (285 and 17 858 C units, respectively), the stoichiometry of C: H is close to 1: 2, which allows us to calculated moles of C in the starting polymers based on their mass. With the information discussed above, the C yield of ...

Polyethylene versus polypropylene: Expect the unexpected
By John Richardson IT IS supposed to be a tale of two polymers with these very different fortunes: Whereas our base case assumes that global polypropylene (PP) operating rates will average a healthy 89% in 2018-2025, we see polyethylene (PE) capacity utilisation at 83%. The higher the operating the stronger the profitability.
