1. 1. An Environmental Approach to PVC Stabilisation

   Författare :Paul Clucas; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic stabiliser; base catalysed dehydrochlorination; colour improvement ; dehydrochlorination stability; polymer-bound stabiliser; intrasequence lactonisation; co-stabiliser; PVC stabilisation; colour stability; labile chlorine substitution; neighbouring group participation;

   Sammanfattning : We were interested in investigating the stabilisation behaviour of 6-aminouracils, a new class of heavy metal free thermo-stabiliser for PVC. We have therefore investigated the performance and mechanism of stabilisation for 1,3-dibutyl-6-aminouracil, both alone, and in combination with a sodium perchlorate co-stabiliser. LÄS MER

3. 2. Enzymatic Synthesis of Alkyl Glycosides. New Applications for Glycoside Hydrolases
