Interactions of PP-PET blends modified by montmorillonite with different polarities

open access: yesPolímeros, 2022
This paper describes the effects of adding organic montmorillonite clays (MMT) with different polarities (one polar and one non-polar) in recycled poly (ethylene terephthalate) (PET) and polypropylene (PP) blends. Styrene-Ethylene/Butylene-Styrene-maleic

Study of the glass transition in the amorphous interlamellar phase of highly crystallized poly(ethylene terephthalate)

open access: yes, 2010
Poly(ethylene terephthalate) (PET) is a semi--crystalline polymer that can be crystallized to different degrees heating from the amorphous state. Even when primary crystallization has been completed, secondary crystallization can take place with further ...
