Proteinbiosynthese und Proteinmodifikationof polymers generally varies from 10. to 10. S cm. at room temperature. The electric conductance depends greatly on the temperature. It is possible to notice an important increase in the specific conductance of polymers above their .. value. Below .., the specific conductance may vary from 10. to 10

Koordinierung des Intermediärstoffwechsels processing and practical applications. Homogenization of these substances with polymers is a very important part of processing technology for the preparation of intermediate products such as granules, agglomerates, pellets, and sheets. This facilitates the final transformation process or increases
