Abstract
(EN)
Disclosed are polymeric compositions comprising polyhydroxyalkanoates. These compositons can comprise a blend comprising a polyhydroxyalkanoate (PHA) polymer, and a rubber polymer. The blend can comprise a biphasic mixture comprising a first phase comprising the PHA polymer, and a second phase comprising the rubber polymer dispersed with the first phase. The rubber polymer can be crosslinked, for example, through reaction with a free radical initiator. By incorporating the dynamically crosslinked rubber polymer, the polymer composition can exhibit one or more improved characteristics relative to PHA alone, including improved thermal stability, improved melt strength, improved flexability, improved toughness, or a combination thereof. Also provided are articles formed at least in part from these polymeric compositions, as well as methods of making these polymeric compositions.

L'invention concerne des compositions polymères comprenant des polyhydroxyalcanoates. Ces compositions peuvent comprendre un mélange comprenant un polymère de polyhydroxyalcanoate (PHA), et un polymère de caoutchouc. Le mélange peut comprendre un mélange biphasique comprenant une première phase comprenant le polymère de PHA, et une seconde phase comprenant le polymère de caoutchouc dispersé avec la première phase. Le polymère de caoutchouc peut être réticulé, par exemple, par réaction avec un initiateur de radicaux libres. En incorporant le polymère de caoutchouc réticulé de manière dynamique, la composition de polymère peut présenter une ou plusieurs caractéristiques améliorées par rapport au PHA seul, y compris une stabilité thermique améliorée, une résistance à l'état fondu améliorée, une souplesse améliorée, une ténacité améliorée, ou une combinaison de celles-ci. L'invention concerne également des articles formés au moins en partie à partir de ces compositions polymères, ainsi que des procédés de fabrication de ces compositions polymères.
