Poly(methyl methacrylate) blends with quaternized polyethyleneimine: A study of morphology, optical, thermal and mechanical properties

Autor: Rafael Affonso Netto, Guilherme Ribeiro de Carvalho, Lucas Henrique Staffa, Liliane Maria Ferrareso Lona

Publikováno v: eXPRESS Polymer Letters, Vol 19, Iss 2, Pp 161-175 (2025)

This study aimed first to promote the alkylation of polyethyleneimine (PEI), developing its alkylated (quaternary) form (QA-PEI) by inserting alkyl groups into amine groups. Subsequently, polymer blends with poly(methyl methacrylate) (PMMA) were prep

Improving UV-C stability in polypropylene through synergistic phenolic or hydroxylamine-based additives with UV absorbers

Autor: Marcos Vinícius Basaglia, Jessica Caroline Ferreira Gimenez, Manoel Gustavo Petrucelli Homem, Sandra Andrea Cruz, Lucas Henrique Staffa, Sílvia Helena Prado Bettini

Publikováno v: eXPRESS Polymer Letters, Vol 19, Iss 2, Pp 124-139 (2025)

UV-C radiation (200–280 nm) is recognized for its effectiveness in disinfection, but it also induces degradation in polymeric materials such as polypropylene (PP), reducing their service life. Stabilizing additives are a viable approach to mitigati
