Study on Performance of PP/POE In Situ Compatibilization

By the in situ compatibilization, PP/POE blends were prepared with dicumyl peroxide (DCP) as initiator, Trimethylolpropane triacrylate (TMPTA) as co-during systems and the metallocene polyolef in elastomers ploy (ethylene-1-octene) (POE) as toughening rubber. The effects of additive amount for TMPTA、POE on the mechanical properties were studied. The results showed that the maximum value of the room-temperature and low-temperature impact strength for the composite was reached to 52.03KJ/m2 and 37.29KJ/m2, and the elongationfor was reached to 482.74%.
