Enzyme catalysis towards bio-based UV-curable buildingblocks
Polymeric materials are found in virtually all areas of daily life; they are found in everything from packages keeping our food safe to the buildings where we spend our days, and the production is a worldwide industry. Although polymeric materials play a big part in sustainable solution’s, a lot can...

Polymeric materials are found in virtually all areas of daily life; they are found in everything from packages keeping our food safe to the buildings where we spend our days, and the production is a worldwide industry. Although polymeric materials play a big part in sustainable solution’s, a lot can be done to develop more environmental methods for producing them. Both the process conditions and the resources that go in are important to consider. As more people understand that we need to manage our planet’s resources and ecosystem differently the demand for sustainable materials is increasing. Catalysis is a key for designing chemistry for the environment and an interesting alternative is enzyme catalysis. Enzymes are proteins working as catalysts in biochemical reactions. One of the most prominent features of enzymes’ is their selectivity, which means that they have preferences towards forming one product over others. Using enzymes’ as catalysts in synthetic chemical reactions the selectivity can be used to produce a wide range of products without side reaction occurring. Further benefits of using enzyme catalysis include high rate acceleration and working under mild reaction conditions. In the work presented here the selectivity and efficiency of enzymes have been combined with photochemistry in new efficient methods for the synthesis ofpolymeric materials. The enzymes used were the well-known lipase B form Candida antarctica and an esterase/acyltransferase from Mycobacterium smegmatis.
