Interactions, structure and properties in poly(lactic acid)/thermoplastic polymer blends [PDF]

open access: yes, 2014
Blends were prepared from poly(lactic acid) (PLA) and three thermoplastics, polystyrene (PS), polycarbonate (PC) and poly(methyl methacrylate) (PMMA). Rheological and mechanical properties, structure and component interactions were determined by various ...

Blending creativity and productivity: on the issue of delimiting the boundaries of blends as a type of word formation

open access: yesLexis: Journal in English Lexicology, 2019
The formation of blends is predictable to a large extent. Moreover, it may give rise to productive constructions where part of a word that was once blended is used to form further blends such e.g.

Fabrication and Characterization of Poly (vinyl alcohol) and Chitosan Oligosaccharide-Based Blend Films

open access: yesGels, 2021
In the present study, we report the development of poly (vinyl alcohol) (PVA) and chitosan oligosaccharide (COS)-based novel blend films. The concentration of COS was varied between 2.5–10.0 wt% within the films. The inclusion of COS added a brown hue to
