1. 1. Lipase-Catalyzed Syntheses of Telechelic Polyesters

   Författare :Magnus Eriksson; Karl Hult; Mats Martinelle; Sergio Riva; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Candida antarctica lipase B; lipase-catalysis; polymerization; telechelic; functional polyesters; ring-opening polymerization; polycondensation.; Biochemistry; Biokemi;

   Sammanfattning : Telechelic polyesters have successfully been synthesized with lipase-catalyzed polymerization. The produced telechelics had a high degree of di­functionalization, high purity (requiring little or no workup) and controlled degree of polymerization. The syntheses were performed in one-pot one-step reaction systems. LÄS MER

   Författare :Stefan Semlitsch; Mats Martinelle; Sergio Riva; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Enzyme; Enzyme Engineering; Biocatalysis; Lipase; CalB; MsAcT; Substrate specificity; Selectivity; Polymer Chemistry; Polymer Synthesis; Bioteknologi; Biotechnology;

   Sammanfattning : The search for alternatives to oil-based monomers has sparked interest for scientists to focus on the use of renewable resources for energy production, for the synthesis of polymeric materials and in other areas. With the use of renewable resources, scientists face new challenges to first isolate interesting molecules and then to process them. LÄS MER
