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

   Author : Peter Löwenhielm; KTH; []
   Keywords : polymer technology;

   Abstract : 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. 22. Designing Polymers for Biological Interfaces - From Antifouling to Drug Delivery

   Author : Pontus Lundberg; Michael Malkoch; Anders Hult; Scott M. Grayson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

   Abstract : Unspecific interactions, at the interface between a synthetic material and an aqueous biological environment, leading to irreversible protein adsorption can cause to undesired consequences. These include fouling of a boat hull or a triggered immune response. READ MORE

5. 23. Influence of the degradation mechanism on the molecular weight changes for some degradable polymers

   Author : Bengt Erlandsson; KTH; []
   Keywords : ;

   Abstract : The influence of degradation mechanism on molecular weightchanges was investigated for certain degradable polymers. Thepolymers investigated were modified low density polyethylene(LDPE), poly(ethylene-co-vinyl alcohol) (EVOH) and aliphatic polyesters. READ MORE

6. 24. Novel Possibilities for Advanced Molecular Structure Design for Polymers and Networks

   Author : Anna Finne; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ring-opening polymerization; coordination-insertion; germanium; cyclic tin alkoxides; spirocyclic initiators; poly L-lactide ; poly 1; 5-dioxepan-2-one ; triblock; star-shaped; network; functionalization; morphology; AFM; Polymer chemistry; Polymerkemi;

   Abstract : Synthetic and degradable polymers are an attractive choicein many areas, since it is possible to control the way in whichthey are manufactured; more specifically, pathways tomanipulate the architecture, the mechanical properties and thedegradation times have been identified. In this work,L-lactide, 1,5-dioxepan-2-one and ε-caprolactone were usedas monomers to synthesize polymers with different architecturesby ring-opening polymerization. READ MORE

7. 25. Synthesis and Properties of Branched Semi-Crystalline Thermoset Resins

   Author : Hans Claesson; KTH; []
   Keywords : star-branched; semi-crystalline; comb-branched; ring-opening polymerization; poly ƒÕ-caprolactone ; dendritic; thermoset; low temperature curing; powder coating; UV-curing; poly 5; 5-dimethyl-1; 3-dioxane-2-one ; size exclusion chromatography; rheology;

   Abstract : This thesis describes the synthesis and characterization ofbranched semi-crystalline polymers. Included in this work isthe SEC characterization of a series of dendrimers. Thebranched semi-crystalline polymers were synthesized in order toinvestigate the concept of their use as powder coatings resins. READ MORE
