Syntheses and Applications
of Thermally Reversible Polymeric Networks
from Vegetable Oils
Frita Yuliati
1. In contrast to a report by Gandini et al., side reactions do occur when reacting vegetable oils with furfurylamine in the absence of a catalyst (Gandini, A. et al. Green Chem. 2013, 15, 1514).
2. Removal of an excess of furfurylamine by evaporation is not recommended (Gandini, A. et al. Green Chem. 2013, 15, 1514). 3. LiBr has a positive effect on the selectivity of the reaction between
epoxidized jatropha oil and furfurylamine (this thesis, Chapter 2). 4. Despite the fact that the Diels-Alder reaction between furans and
maleimides is fast (Wei, H. L. et al. Polymer. 2009, 50, 2836–2840), longer reaction times are required to make cross-linked polymers. 5. Although the concept of using thermally reversible covalent bonds is
very useful in designing recyclable polymers, more research is required for large scale introduction of such polymers in industry (Engle, L. P. et al. J. Macromol. Sci. Part C. 1993, 33, 239–257)
6. The synthesis of materials from renewable resources can still be a burden for the environment as significant amounts of energy are required (this thesis, Chapter 4).
7. The products of years of research may seem useless, however, the scientific results behind them may be useful.
8. Finishing a PhD boosts confidence as well as self doubt.
9. People from different cultures behave like fluids with different polarities. Considerable efforts are needed to improve interactions. 10. The reaction between two Diels-Alder adducts are comparable to a
relationship between two people. When the chemistry is right, a bond can be formed under mild conditions. It is broken upon increasing temperatures but can be mended when being cooled to a certain level. Overheating can produce an unbreakable bond between the adducts, whereas for people, it can be permanently broken.
11. When your supervisor says “jam karet” to an Indonesian, you should worry.
12. You are very direct for an Indonesian (Picchioni, 2015). I take that as a compliment.
13. By nature, gossipers are useful for free public relations.
14. I travelled far in search of happiness, only to find it within myself. 15. To you be your way and to me mine (109:6).
