摘要
We investigated the changes in morphology of medium and high molecular weight polyhydroxybutyrate blends (MMWT/HMWT PHB) during shearing, using various in-situ theological methods. On single shearing, fibres were formed only at the highest MMWT/HMWT ratio of (97/3). This was attributed to a critical orientation molecular weight. Fibre formation took place with all compositions and there was a rapid initial shish formation on multiple shearing. This is evidence for a partial shish based on the Janeschitz-Kriegl model.
