Effect of maleic anhydride on mechanical properties and morphology of poly(lactic acid)/natural rubber blend [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2020
Natural rubber grafted with maleic anhydride (NR-g-MA) was synthesized in an internal mixer at different loadings of MA content. NR-g-MA was used as a rubber modifier of poly(lactic acid) (PLA) and a compatibilizer of PLA/NR blends. Polymer blends were

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 ...

A comparison between the morphology of semicrystalline polymer blends of poly(ε-caprolactone)/poly(vinyl methyl ether) and poly(ε-caprolactone)/(styrene-acrylonitrile) [PDF]

open access: yes, 1994
The morphology of polymer blends of poly(ε-caprolactone) (PCL) and poly(vinyl methyl ether) (PVME) is compared with that of PCL and a random copolymer of styrene and acrylonitrile (SAN).

Evolution of polymer blend morphologies during extrusion in a flat die [PDF]

open access: yes, 2009
The control of blend morphologies during process is of prime importance in order to predict the final properties of polymer blends. A coextrusion technique combined with static mixers was developed in order to smartly blend polymeric melts and to ...
