Dynamically vulcanized polylactic acid/natural rubber/waste rubber blends: Effect of the crosslinking agent on the morphology and tensile properties
N Candau, NL Albiter, PR Coll… - Journal of Applied …, 2022 - Wiley Online Library
Abstract PLA/natural rubber (NR)/wastes tire rubber (GTR) were dynamically vulcanizing
using dicumyl peroxide (DCP). Swelling, dissolution, and electron microscopy revealed that
the unvulcanized and weekly vulcanized blends (DCP< 3 wt%) show a continuous rubber
phase while the highly vulcanized blends (DCP> 3 wt%) show co‐continuous rubber/PLA
phase. In the latter blends, the tensile toughness (1.3 MJ m− 3) and the tensile‐impact
strength of the neat PLA (58 kJ m− 2) were increased of a factor 12.5 and 8.3 respectively …

Dynamically vulcanized polylactic acid/natural rubber/waste rubber blends: effect of the rubber content
N Candau, N León Albiter, H Jeannot… - Journal of Materials …, 2022 - Springer
The reduction in the production of conventional polymers based on crude oil by using bio-
based plastics and by valorizing rubber wastes is an essential route to reverse the negative
impact of the polymer industry on the environment. To contribute to this challenge, we
prepared polylactic acid (PLA)/natural rubber (NR)/ground tyre rubber (GTR) blends via
dynamic vulcanization. The PLA/NR/GTR blends with a rubber content and above 30 wt%
show a continuous rubber phase (NR/GTR) where the GTR particles are encapsulated into …
