Compatibility in the sense of a tendency to molecular mixture and mutual solubility is rare for two solid polymeric components. Thus, not only mixtures but also graft and block copolymers constitute two phase systems. Possibilities for identification of separate phases are discussed, including optical methods and determination of freezing and melting temperatures of the individual phases. Problems of preparation of two phase mixtures and the phase distribution arising thereby, including identification of disperse and continuous phases are discussed. Examples are given of little known polymer mixtures for which complete or partial compatibility exists.
In this publication heat transfer in microstructure devices and its application in laboratory and industry will be described. Basic principles of microstructure heat exchangers made of metal, ceramics and polymers will be presented. A variety of laboratory prototype applications will be shown as well as some examples for industrial use of not only microstructure heat exchangers but also microstructure devices as chemical reactors. A brief outlook will describe possible future application fields.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
