Formation of Block Copolymer and Surfactant Vesicles

In this thesis temperature induced vesicle formation in both a block copolymer system and nonionic surfactant system have been investigated. The block copolymer is a triblock copolymer of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO), PEO-PPO-PEO, with the average molecular composition of EO5PO68EO5 and the commercial trade name Pluronic L121 (papers I, II). In the L121 system the for

Granulation and recycling of polymers

The use of polymers and composite materials based on polymer matrix systems increases. With this raise the demands on recycling of both post-consumer and in house based material increase. The demands on the recycling process also increase. The reason is that the process more often has to be a part of the conventional production line. In order to incorporate such a process in a production line tech
