Polyolefins waste-based blends obtainedthrough reactive mixing process

The recent growth of plastics recycling presents an opportunity for developing new value-added blend products from post-consumer recycled polymers. In general, high performance in properties such as high impact strength, ductility and solvent resistance are highly desirable in a polymer blend to enhance its value and application potential. However, in the majority of the cases, attaining these requirements with recycled materials is very difficult because of several reprocessing problems, in which degradation plays a significant role. Another important problem in recycling is that most polymers are incompatible, and therefore blends have poor mechanical properties.

Zbadano wpływ reaktywnych modyfikatorów z różnymi grupami funkcyjnymi na morfologię, właściwości reologiczne i mechaniczne blend na bazie odpadowych poliolefin wytworzonych w procesie wytłaczania. Przedstawiono wyniki właściwości mechanicznych, lepkosprężystych oraz zdjęcia z mikroskopu elektronowego.
