3. 2. Branched aliphatic polycarbonates : synthesis and coating applications

   Författare :Peter Löwenhielm; KTH; []
   Nyckelord :polymer technology;

   Sammanfattning : The overall aim of this thesis is to describe the synthesisof branched aliphatic polycarbonates and show the potentialapplication of these polymers in the field of powder coatings.The characterization of the polycarbonates was facilitated bythe study of a series of bis-MPAdendrimers, which served asreference of perfectly branched polymers.

4. 3. Free radical mediated cellulose degradation

   Författare :Erik Johansson; KTH; []
   Nyckelord :free radicals; cellulose; polymer; average chain length; bleaching; TCF; ozone; degradation;

   Sammanfattning : This thesis addresses the mechanisms involved in cellulosedegradation in general and Totally Chlorine Free (TCF) bleachingof pulp in particular. The thesis shows that the cellulosedegradation during high consistency ozone bleaching is explainedby free radical chain reactions. LÄS MER
