1. 11. Solvents and solvent blends for the polymers TQ1 and N2200.

   Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Författare :Lisa Lundin; [2019]
   Nyckelord :;

   Sammanfattning : Abstract The solubility of polymers depends on how well the parameters of the polymers and solvents used resemble each other. The more similar the parameters are, the more likely the polymers are to be dissolved. LÄS MER

3. 12. Analysing and concluding the cost/performance matrix for biopolymer blends with different renewable contents

   Master-uppsats, Lunds universitet/Centrum för analys och syntes

   Författare :Linda Ehrenberg; Filip Nilsson; [2018]
   Nyckelord :biopolymers; polymer blends; PHA; PBS; PLA; PP; compounding; blends; cost; price estimations; renewable content; feedstock; polymer technology; polymerteknologi; Technology and Engineering;

   Sammanfattning : Due to increasing awareness and consumer demands it has become important for companies to develop an economical and environmentally sustainable alternative to traditional petroleum-based plastics. The transition from fossil material to bio based is important for the future of people and planet, still, how the transformation should be implemented is yet unknown. LÄS MER

4. 13. Investigative study of Biopolymer contamination in conventional recycling systems

   Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

7. 15. Investigation of the native starch-ethyl cellulose film coating for colon targeting

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Livsmedelsteknik och nutrition (master)

   Författare :Mohamed Esmael; Ali Majid; [2016]
   Nyckelord :starch; colon delivery; pharmaceutical technology; läkemedelsteknologi; Chemistry;

   Sammanfattning : The aim of this study was to optimize a function starch-ethyl cellulose film for targeting the therapeutically active substance to the colon in the disease state for patients suffering from inflammatory bowel diseases. This study includes: • The preparation of the polymeric films and the investigation of the characterization (for example mechanical properties, water uptake, dry mass loss, and microscopy analysis) for these prepared film coatings.
