I am trying to raise the melt viscosity of a PHA polymer however as it is microbially produced the MW is already very high and difficult to control, and the addition of crosslinking agents will compromise the biodegradation credential.
Dear Anand J Gaston, you can blend it with PLA, or use fillers such as talc for example. My Regards

Hi
Dear Anand J Gaston
It may be possible to solve both the viscosity problem and the compatibility problem by adding fillers of biocompatible polymers such as poly (lactic acid-co-glycolic acid). Temperature reduction is also recommended.
My regards.
