Plants to Polyelectrolytes: Theophylline Polymers and their Microsphere Synthesis [PDF]
Macromol. Rapid Commun. 2017, 38 (8), 1600748, 2017 To extend fossil oil supplies, sustainable feed stocks for the production of useful reagents and polymers should be harnessed. In this regard, chemicals derived from plants are excellent candidates. While the vast majority of plant sources used for polymer science only contain CxHyOz, alkaloids such as caffeine, nicotine, and theophylline possess ...
