NettetThermoresponsive Linear Polyglycerol Synthesis (N 3-tPG-N 3) Polyethers such as linear thermosensitive polyglycerol (tPG) are suitable candidates for the design of nanodevices due to their biocompatibility [39,40] and versatility [41,42,43]. NettetIn this paper, we show for the first time the production of a library of linear polyesters derived from the model polyol sorbitol and a small selection of diacids combining K 2 CO 3 as an inexpensive and readily available catalyst and scCO 2 as the reaction medium to enable mild reaction conditions.

Nettet11. feb. 2024 · A brief outline of polyglycerol chemistry can be given by looking at the following table where the linear oligomers of glycerol are described. In polyglycerols, the number of OH groups corresponds to the degree of oligomerisation plus 2; therefore, diglycerol (n=2) has 4 OH groups and triglycerol (n=3) 5 OH groups etc. NettetVi vil gjerne vise deg en beskrivelse her, men området du ser på lar oss ikke gjøre det. state wise food images
