2. 1. Controlled Degradation of Polyester-Ethers Revealed by Mass Spectrometry Techniques

   Author : Anders Höglund; Ann-Christine Albertsson; Jukka Seppälä; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Degradation products; biocompatibility; -caprolactone; 1; 5-dioxepan-2-one; 6-hydroxyhexanoic acid; 3- 2-hydroxyethoxy propanoic acid; oligomers; Polymer chemistry; Polymerkemi;

   Abstract : The use of degradable biomedical materials in e.g. tissue engineering and controlled drug delivery has changed medical science during recent decades. The key question is to adapt the material with respect to mechanical properties, surface characteristics, and degradation profile to suit its intended application. READ MORE

4. 2. Aliphatic Polyesters for Soft Tissue Engineering : Development from Conventional Organometallic to Novel Enzymatic Catalysis

   Author : Rajiv Kumar Srivastava; Ann-Christine Albertsson; Stanishaw Penzzek; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; aliphatic polyester; 1; 5-dioxepan-2-one; ε-caprolactone; L-lactide; D-lactide; D; L-lactide; enzyme; lipase CA; lipase PS; Polymer chemistry; Polymerkemi;

   Abstract : The development of macromolecules with defined structure and properties, aimed specifically for biomedical applications, has resulted in diverse biodegradable polymers with advanced architectures. Among them, aliphatic polyesters synthesized by ring-opening polymerization (ROP) of lactones and lactides have a leading position due to their good mechanical properties, hydrolyzability and biocompatibility.

5. 3. Graft polymerization

   Author : Torbjörn Lindberg; KTH; []
   Keywords : ;

   Abstract : This thesis is focused on morphological aspects of polymericsubstrates used in graft polymerization. Morphological changesof selected polymer systems were investigated in the virginstate and after irradiation, during the progress of graftpolymerization, in the final grafted state and duringsubsequent degradation.
